We use a grab-bag approach. We have a dead simple schedule:
Pasta Monday
Taco Tuesday
Egg Wednesday (frittata, quiche, scrambled eggs)
Fish Thursday
Pizza Friday
Saturday and Sunday are open days but frequently Saturday is a stir fry or some grilled meat and vegetable. Sunday is meal prep day, frequently soup, stew, chili or maybe some rice and beans and chicken.Before quarantine, I meal prepped work lunches on Sunday, and also would bake fun things like muffins, etc. Breakfast is dead simple -- eggs, toast, coffee, oatmeal, cereal, yogurt, granola (depending on the family member).
We also buy in bulk from Costco and store, particularly for shelf stable things (plus a deep freezer). Most of our base meals don't involve a recipe (pizza Friday is typically Costco frozen, one cheese for kids and one caulipower for adults). We use paprika app to store new recipes (mostly for weekends / parties), and reserve the weekend for making fun or time consuming things. I also liberally add to recipes as needed. For example, my chili wasn't just a slop of ground beef and cheese but had quinoa, corn, sweet potatoes, tomatoes, peppers, jalepenos, zucchini, sausage, etc. I just made a soup recipe and added corn, wild rice and peas. I made it twice the size, and I'm going to fill up some mason jars for the freezer (leave room on top esp. for soup b/c water expands as it freezes).
We work from staple recipes. Like we make pancakes a ton, never waffles. I make hummus a lot and can do various types -- the point was just to learn something that I could again and again on repeat for parties. Then there's plenty of things I've never made. On motivated days, we can add shrimp, vegetables, etc. to the pasta but on rough days everyone gets a bowl with pesto and peppers and you eat what you eat and don't get upset.
