This falls into the category of make-ahead meals, which has many options! Prep and marinate fresh meats like chicken or beef, then place into ziploc sandwich bags, gallon bags, or storage containers.
For example, I like to add my marinade to chicken, place into sandwich bags, let marinate all day or overnight in the refrigerator, then if I’m not going to use it all, I’ll place the extra bags in the freezer. Flatten the meat and stack them (as much as possible) so you can utilize the best freezer space.
The same concept goes for ground meats. Season the meat and form into patties, meatballs, or small loafs (meatloaf). Then you have fresh meat ready in your refrigerator or freezer for quick meals!
If you don’t want to refrigerate or freeze the raw meat, cook batches of the marinated / seasoned / formed meat, then portion and keep in the refrigerator or freezer. This might be half or a full day’s worth of work (or recruit help) but you can meal prep for 1-2 months at a time. Have fun with your seasonings and create several! Don’t forget to label the bags or storage containers with the name and date of the items.
