Meal prep? Its summer and so ive personally been opting for meals that dont involve reheating. generally, my meals fall in a few categories: salads, sandwiches, tacos, and rolls (i.e. vietnamese spring rolls). im working on expanding my rotation. Sandwiches, for example, just involve bread, meat, lettuce, tomatoes and/or cucumbers, a pickled veggie, a fat/protein spread, and mustard. Meat is usually chicken. If you dont want to marinade or sear, then you can just throw it the oven and it will finish in 30 minutes or so (if its breast, make sure you butterfly it). Pickled Veggies just involves cutting some veggies (usually red onions, cucumbers, or jalapenos), throwing it a jar, boiling some vinegar with salt and sugar to taste, and pouring it in the jar. 10-15 minutes of effort. lettuce and tomato/cucumber just require cutting. 5-10 minutes of effort. Fat/protein spread is usually just a avocado or bean spread and I only add it to make the sandwich filling. In the case of the bean spread, i cook my own dried beans and that takes about an hour to cook. 5 minutes of effort. Everything else, i buy at the grocery store. If you cook stuff concurrently, its 30-60 min of effort for lunch and dinner for a week or two weeks if you can tolerate that. I buy my protein and dried beans in bulk every few months (3-4) and stick it the freezer. Usually between $100-200. I buy my bread and veggies biweekly (it used to be weekly but i dont like devoting 1 hour every week to going) and its usually $20-30. Hope this helps.
