If you haven't tried Esme's simple sauce, you must! It's equal parts tahini, miso, nutritional yeast (or mustard), soy sauce, lemon juice (or vinegar), olive oil and a little crushed garlic. Delicious on pasta as seen here. For best results, heat above ingredients in a saucepan and stir til thickened, adding a little water if too thick, then toss with pasta. (I use about 4 TB of each ingredient.)
I accidentally over-roasted my yellow squash, carrots and potatoes. Oops.
