*Meal prepping salads is my favorite thing. I would recommend doubling the amount of chicken and then buying double the amount of produce. I normally buy a large container of mixed greens, a bag of avocados, 1 lb of strawberries, and I have lots of nuts and feta on hand always. Slice up as much red onion as you desire for the week and store in a bag in the fridge. I also would double the balsamic vinaigrette dressing and keep it in the refrigerator throughout the week. Assemble the salad every day whenever you choose to keep it fresh. You can also store a pre-dressed salad, but I would eat it within 24 hours so it doesn't get too soggy.
