I've been doing slow cooker chicken/pork, side beans, and coriander rice in my prep time on weekends and buying tortillas, corn chips to make nachos, tacos, burritos and enchiladas. Each night I'll use some of the ingredients and substitute in different items to make it taste like a new meal. Creamy with sour cream one night, spicy with jalapeno the next, melted cheese sauce. I froze half the slow cooker meat to use at a later time. Similar dishes like Korean bimbimbap are handy as you can add different opinions each time; egg, grated carrot/zucchini, tofu, bean sprouts, kimchi, green veg over rice with a protein. Keeps me interested but without feeling like it's the same meal over and over.
