We're a family of 4. I do most of the cooking, though DH does grill a lot. With kids activities, we have to have a lot of quick and easy options, and kind of have a set schedule for carry out, cooking and dining out. I also only go grocery shopping once a week (Saturday or Sunday morning), so I plan all the meals out in advance generally. I will buy meat in bulk at Costco for the good quality, but that takes a lot of storage space. I only do elaborate meals about once a week, usually for Sunday dinner. Otherwise I stick to the boring formula I grew up with 1 protein, 1 starch, 1 or 2 vegetables..... or the dreaded casserole with a salad.
PPs have mentioned giving cooking another try. I have to agree. My mother was a wretched cook. I learned the hard way that being a decent cook is all about following directions. For learning the basic techniques, I recommend the Betty Crocker cookbook (2000 edition) and Joy of Cooking (1975 and 1997 editions - I'm not wild about the 2019 edition). For grilling, Weber kettle cook books tend to cover the basics. And if you want to get really basic - try getting a copy of "The Best of Cooking with 3 Ingredients" by Ruthie Wornall. It's literally a cookbook written by a woman who got married and didn't know how to cook. Anyway, start simple. And if you aren't dealing with a lot of dietary restrictions, there are tons of inexpensive, easy to prepare options. The McCormick seasoning packets are a good starting place - just follow the directions. Shake n Bake or Hamburger Helper is your friend.
We tend to do sandwiches, soups and salads for lunch. When we get extra bored of that I tend to do large yield casseroles to reheat for either lunch or dinner (I cut it up into serving sizes and freeze it too. Or ramen with a protein like a fried egg, boiled egg, canned chicken, frozen chicken puck/patty and a salad.
Anyway, we have a home cooked dinner on Sunday, Monday, Tuesday, Wednesday always.
Thursday is carry out night - always pizza or Chinese - and we order enough so DH and I can have the leftovers for lunch on Friday.
Friday night is usually our dinner out night.
Saturday is frequently a more involved grilling dinner night.
In hot weather, we do a lot of this formula:
1. grilled boneless chicken thigh (in store bought marinade) / grilled italian or german sausage / grilled steak (in store bought rub) / grilled fish / baked breaded chicken tenderloins / panfried ham steak / ground beef tacos / baked breaded turkey cutlets
2. plain rice cooker white rice / boxed quick cooking rice pilaf / couscous / pastaroni / pierogies / instant mashed or au gratin potatoes / baked potatoes / canned seasoned or baked beans
3. fresh or frozen green beans / squash / broccoli / carrots / brussels sprouts / corn / green salad / cole slaw
In cooler weather, I do more casseroles or large batch items I can stew in the instant pot: beef stew using McCormick seasoning and biscuits, chili with cornbread, beefaroni, lasagne, baked ziti, homemade macaroni and cheese with ham cubes, chicken ala king over rice, chicken bot boi, goulash with egg noodles, etc. Frequently serve these with a bagged/boxed salad on the side.
