Tessa Kiros' Twelve cookbook has been my go to for simple meals. Her Spaghettini aglio, olio e peperoncino (spaghetti with garlic, olive oil, and chili) seems to go with everything you might have on hand in the house. The sauce recipe calls for 1/2 cup olive oil, 3 cloves of diced garlic, a handful of chopped parsley (fresh is called for, although dried seems fine to me), and 3 small crumbled red chilis (I use a couple of shakes of the dried chilis from the shaker). That's it. You can add some peas or halved cherry tomatoes to the sauce at the very end. Then toss it with whatever pasta you have in the cupboard. My husband always loves it and it is super easy!
