Sweet Potato, Black Bean, and Quinoa Tacos with Avocado and Lemon Tahini Sauce #vegetarian #vegan #meatlessmonday

It’s Monday and we’re all groggy from daylight savings, but looky here: we’ve got tacos!

Do you ever say to yourself, “I want a taco right now, and I need it to be meatless?” I typically like my tacos oozing with saucy meat, but I’ve needed to take a brief hiatus from the animal lately on account of the fact that I’ve been eating so dang much of it. I mean, have you been around here the last couple of weeks? It’s been a real animal house.

In honor of my meat hiatus, I have a Meatless Monday meal for you! I made us a taco that’s loads better than loosing an hour of sleep, right up there with the new Rihanna, Kanye and McCartney song, and almoooost as good as two of my favorite artists, Zac Brown and Chris Cornell, singing a little ditty together.

This is a simple, super filling, and tasty recipe to keep you fed throughout the workweek. You can prepare any of the ingredients ahead of time and eat on them for lunch or dinner.

Yes, you will use all sorts of pots and pans in the making of these tacos, but the actual effort you put into the prep is child’s play, I promise.

Just as the title suggests, our meatless tacos include quinoa, black beans, roasted sweet po’s, some avo, and green onion. The lemon tahini sauce is what really seals the deal, so be sure to make it a priority.

Or whip up your sauce of choice, like guac, salsa, queso, cashew cream, what have you. What I’m getting at, is sauce is really what makes these things gravy. Make it saucyyyyy!

    Hooray for daylight savings! I can taste summer. I guess I need to get a pedicure in anticipation of flip flops. And maybe lift some weights so my arms are tank top ready! And shove tacos in my face. Yeah. Going to go and do all that right now!!

  2. Abby @ The Frosted Vegan

    These are the tacos of my dreamssss!! So my favorite taco place (just a block from my house, bad/not bad) stopped making my favorite taco and it was JUST like this one! Totes making these for dinner so I can pretend it’s almost summer, because I really just neeeeed it to be summer already!

      WHY WOULD THEY STOOOOOOP?!! Well sheesh, guess that means you and I will just have to make deez tacos together in bulk…wanna meet somewhere in middle USA?

  3. Sarah @ Making Thyme for Health

    Ooooh these tacos are my jam! I want to shove 3 in my mouth at once and then wash them down with that lemon tahini sauce.

    And can we talk about how jealous I am that you live so close to Lake Tahoe? I love that place so much it makes me want to cry. I need to start planning a weekend there soon so we can hang out and drink white wine in red solo cups. 🙂

    Daylight savings time is the best. I don’t even care that we lost an hour of precious weekend time because it will no longer be dark when I leave work! And these tacos – yum! I always have tahini on hand but I never thought to use it with tacos!

    1. Julia Post author

      This was my first go-round using tahini on tacos, and I was surprised how well it just worked! Let me know if you try it!

    Daylight savings drives me crazy. I do like it to stay light later. However, in the last 10 years or so they’ve added two months to the length. It makes calling standard time standard nonsensical, since we’re now spending 8 months of every year on daylight savings time!

      It’s very strange, indeed. I saw this video on Facebook: https://www.youtube.com/watch?v=br0NW9ufUUw which gave me a good laugh. Funny how we hold on to traditions that don’t make a lick of sense. What really gets me is how some states observe DS and some don’t…Although I love the extra hour for snapping photos, I’m thinking we just need to kick DS to the curb 😉

    “I want a taco right now” is pretty much my mantra. I could seriously eat tacos every. single. day. Yeah, I’m all about the sun staying out a little longer. Also, it’s 45 degrees here, which is pretty much summer compared to last week. I even thought about digging out my flip-flops. Girl, gimme all the tacos. Pinned.

    1. Julia Post author

      I knew I’d be in good company on the taco front. Who are the people who don’t like tacos, is what I want to know. 😉 YES to 45 degree weather after the arctic freeze y’all have been having! And yes to flip flops…can we call them thongs just for fun?

  8. Stefanie @ Sarcastic Cooking

    We have been eating so many tacos lately! I am all about them! They are so easy and versatile. I can’t wait to serve andy the quesadilla version of this because he loooves both these veggies! Oh and thank you for giving me a new song to like!!!

    1. Julia Post author

      Yeeeeeah so glad you like that song!! I love all the musics, and figured the Zac and Chris duo would be a little too hard for more people, but shiiii man…it’s just too good not to share. YES to the queso version of the recipe!! You’s brilliant, m’dear!
