Some sources that I refer to quite a bit for quick meal prep:
Robin Miller from the Food Network has a show called Quick Fix Meals. She does some more in depth cooking and prep on the weekends (maybe 30 min) and then puts together 15 minute meals on weeknights. Her show notes list the recipes for the week, the grocery list, and provide step by step instructions on what to do to get prepared.
Cooking Light also has a Quick & Easy Meal section of their webpage. They have some great recipes. Additionally, they have 2 books Superfast Foods and 5-ingredient 15 Minute cookbook which are great for quick meal prep.
I have been experimenting a bit with some quick meal options. One of my favorites to make is Fish in Parchment Paper.
Basically, take some fillets of white fish (trout, tilapia, or whatever happens to be on sale), add in some vegetables - I like to use leeks and carrots, sprinkle some seasonings - for me: salt, pepper, minced garlic, and thyme or dill, and then drizzle olive oil (or throw in a pat of butter) over the top.
You can wrap up the packets and either freeze them or else refrigerate them for a day until you are ready to use them and then just pop them in the oven at about 425 degrees and depending if they are fresh or frozen - it takes 10-25 minutes to cook. Then just open up the packets and enjoy.
