Caramelized Onion, Spinach, and Avocado Quesadilla

It’s not every day I show you a quesadilla. In fact…I’ve never shown you a quesadilla. Why haven’t I shown you a quesadilla? There are no reasons.

Caramelized Onion, Spinach, and Avocado Quesadilla #vegetarian #healthy #recipe


This crispy-on-the-outside-smoosh-on-the-inside quesadilla is a souped up version of your childhood favorite. It’s all grown up with rich caramelized onions, Vitamin-ed out with spinach, and a real tear-jerking dream boat with thick slices of avocado.

Caramelized onions are my love language.Β 

Caramelized Onion, Spinach, and Avocado Quesadilla

I want them on all the foodstuffs. I can neither confirm nor deny my burning desire to eat caramelized onions on ice cream. They may take light years to make, but they are worth their weight in gold. Plus you can watch an entire re-run of Gilmore Girls while letting your onions become fancy. It’s a low-maintenance method for putting the artisan in your tortilla.

I know what you’re thinking. Gluten. Gluten-y glutenous tortillas. We don’t really do glutenΒ here, like ever. But never fear: if you’re gluten-averse, Β simply use your favorite gluten-free tortillas for this recipe. Or replace the tortilla with caramelized onions. Totally comparable substitution.

Put your fancy pants on and waltz over to Oh My Veggies for my Caramelized Onion, Spinach, and Avocado Quesadilla Recipe.

      Oh yes. There will be no ‘dilla-ing without the fancy pants on πŸ˜‰ Okay, truth: I ate this thing after a mountain bike ride and I was still wearing my padded shorts and there may have been a lot of sweat involved. But that’s neither here nor there.. πŸ˜‰

    I will definitely be replacing the tortilla with caramelized onions, that is a genus idea, haha! I have a special place in my heart for quesadillas and an even more special place for quesadillas that are dressed up with delicious ingredients like avocado, spinach, and caramelized onions πŸ™‚

      Hmmm…now that I think about it, selling fancy quesadillas over the internet could be a lucrative enterprise…but for you, my dear, I deliver for free πŸ˜€

    I speak in caramelized onion tongues also! I feel like we should create our own caramelized onion-based society. Think of how happy our bellies would be.
