I've cooked hamburger with seasoning in my CI, drained the fat/oil, then added a jar of Prego to make Spaghetti. Let is simmer while I boil the water for the noodles.
Lately I've been buying split chicken breasts, deboning them, cutting them into 3/4" cubes, and marinating them in various sauces/spices. Then cooking them in the CI with a bit of oil. Once cooked I add a jar of Trader Joe's simmering sauces. While the chicken is cooking and simmering, I cook some Basmati rice in my Rice Cooker.
Oh yeah, I LOVE to fry some bacon in my CI, drain most of the oil/fat, then cook some scrambled eggs in the residue.
