Cook the spaghetti squash according to these instructions, and prepare the pesto sauce.
When the spaghetti squash is about 10 minutes from being finished, saute the vegetables. To do so, heat the avocado oil in a large skillet over medium heat. Add the carrots and broccoli and stir well. Cover, stirring occasionally, until vegetables reach desired done-ness, about 5 to 8 minutes. Add the spinach, cover, and continue cooking until wilted, about 2 minutes
Once the spaghetti squash has finished roasting and is cool enough to handle, use a fork to release the "spaghetti" strands, then add them to the skillet with the sauteed vegetables. Add the pesto sauce and sea salt and stir well. Taste the veggies for flavor and add more pesto sauce or sea salt to taste.
Turn the oven on the high broil setting. Lightly spray or oil a casserole dish and place salmon fillet in it. Drizzle salmon with avocado oil and use your hands to smooth it over the flesh so that all the flesh is lightly coated in oil. Sprinkle with paprika, ginger, and sea salt.
Broil on the second to the top shelf of the oven for 10 to 15 minutes (depending on thickness of fish), until salmon is golden-brown and crispy. Allow salmon to rest 5 minutes before cutting into smaller pieces for serving.
Divide the spaghetti squash and sauteed vegetables between 2 or 3 bowls. Top with crispy salmon and serve.
