It's a tough thing to start. I don't like eating the same thing everyday so I don't make 10 servings of chicken and broccoli at once. So I mix mine up a little bit.
I buy maybe 1 or 2 packs of chicken breast or thighs. That's about 10 pieces of meat. I'll put different seasonings on em about 3 a piece to a seasoning. I'll bake those.
Then I'll take a pack of ground beef or turkey and I'll make a separate dish with that on the stove with some rice and beans, sometimes spaghetti with veggie noodles.
So I end up with a good 12-13 meals there with only 3-4 dishes to clean. The main thing is limiting dishes you have to clean
I don't really prep veggies cause they're easiest to cook anyway and don't take time.
Now if you have a slow cooker or crock pot then that's a whole nother level
not bad considering it's my 1st time trying it. I was good with 225 but I might try to go up a little more
