This is one of the most fabulous comfort food-type dinners I've made in a while! This is really something you HAVE to try. I based my recipe off of this recipe by Emily Malone. Her recipe calls for mushrooms as the bulky base of the sauce, but I already had mushrooms at lunch . . . SO I replaced the mushrooms with Boca Crumbles, left out the non-dairy creamer (partially because I didn't have any) and ended up with a savory, creamy, cheesy, stick-to-your-guts sauce. Plus, I accomplished my goal of adding a "meaty" protein to round out the meal. I really liked Emily's technique for cooking the spaghetti squash; instead of scooping out the gooey seeds and membrane AFTER baking it in the oven, she cuts it open BEFORE, scoops it out, and rubs the insides with chopped garlic and a little olive oil. So I prepared mine just like that for a little over an hour and it came out perfect. While that was in the oven, I sauteed some garlic and onion in a pan with non-stick spray. I added my Boca Crumbles, cooked it for a few minutes, then poured in about 1/4 cup unsweetened almond milk. I let that cook down and thicken up a little, then I added about 1 1/2 T nutritional yeast :). I added a little more almond milk (about another 1/4 cup)and 1/2 teaspoon of cornstarch that I previously mixed with some water (DO NOT add the cornstarch directly to the sauce). Finally, I seasoned it with a little salt and pepper- that's it!! I must say- I never got why nutritional yeast was described as "cheesey", and now I definitely do. This sauce is the reason I will definitely be incorporating it in future recipes.
