One-pot meals are a favourite of mine, as they cook quickly, minimize washing up, and allow you to experiment with a variety of different ingredients and leftovers. Tonight I combined rigatoni with leftover pasta sauce, raw cabbage, cooked chickpeas, nutrititional yeats, and Gardein chicken nuggets. How much you put in the pot depends on how many servings you want. The key is to add all the dry ingredents, then add enough water to cover everything, then the pasta sauce. Bring to a boil, cover the pot, and cook over medium low heat until the pasta is cooked. You need to stir occasionally to prevent the pasta from sticking to the pot. The result was delicious, and my cats licked the bowl clean.
