Boil your pasta to desired softness, then strain and toss with olive oil and a pinch of salt. Optionally add a hefty pinch of dried basil. Optionally boil with sweet potatoes or regular potatoes diced to 1/2" cubes or smaller in at least the last seven minutes. If you add chopped carrots, they will cook in about 3 minutes. Note: I cover my pasta when cooking with additions.
Fry 1/2 a diced onion and 3-4 large cloves of chopped/minced garlic in olive oil over low, preferably in a cast iron pan. Optionally add black beans, chicken or other meat, frozen veggie mix, or greens to fry as well, if you add greens, add a little water (like a few tablespoons) for steam, then cover and let cook.
For the sauce, add about 1/4-1/2 cup of crushed tomatoes to the fried onions along with salt, ground black pepper, big pinches of red pepper flakes and dried basil, and preferred italian herb, though not usually sage, plus more olive oil. Take the sauce and mix it with the pasta, it should barely cover the pasta and have an oily sheen. If there's not enough oil, you can add more. The olive oil is a big part of the flavor. You can also add a pinch of sugar or some honey, but I find tomatoes are already pretty sweet.
Voila! Starvation avoided. Serve with a fried egg if desired.
Don't add too many extras, if you add black beans of course it's going to taste kinda like chili.
