We don't focus on food prep in our house much. We both work, and sometimes dinner is leftovers of whatever we had a day or two earlier, sometimes it's takeout, sometimes we don't get to eat together, and so it goes.
Yesterday's dinner: my wife had made bulgogi (Korean seasoned) pork tenderloin last week sometime and we had leftovers in a container. We also had leftover rice in a container. We chopped up a few onions and a couple of big orange peppers, sauteed for a while in olive oil with a bit of salt and pepper and a few cloves of fresh garlic. Erstwhile we put some water and some soy-sauce-like things on the rice, mushed it up with our fingers, and warmed it a little in the microwave to encourage the liquid to get into the rice, which was kind of dry.
Dump the rice into the skillet with the onions and peppers, warm/sautee a bit more, season a bit more, add the pork, leave that long enough to warm up a bit, then serve with chopped scallions, parsley, and cilantro on top. My wife and I cooked together, and it was a pretty yummy result.
Nutritional breakdown - unknown. My point is that we used a couple of different leftovers and a few fresh ingredients to make a tasty dinner.
NB: Neither of us is Korean or has ever visited Korea, but if you haven't had bulgogi, you're missing something, and it's just a matter of having the right seasonings to be able to make it at home. We are fortunate to have two excellent and inexpensive Korean restaurants in our little town here in NJ and learned about bulgogi first by having it as take-out.
We keep a few things in the freezer most of the time: breaded chicken tenders; breakfast-type sausages; ground grass-fed beef. And in the fridge or the pantry, we try to keep fresh parsley, fresh cilantro, some onions, and some peppers. And rice which we make in an Instant Pot. With those things, you can create a whole lot of tasty things to eat. Dry pasta sometimes instead of rice, sometimes cheese and/or tomato sauce with the protein and pasta. And salad makings - one or two kinds of argula/lettuce/kale, cucumbers, tomatoes.
