Heat a large heavy-duty pan to medium-high heat (1-2 minutes). Add 1 teaspoon oil to pan. Season chicken breasts with salt and pepper and cook chicken in pan until golden and cooked through, 5-6 minutes per side. Remove from pan and cool for 5 minutes then chop into chunks or slices. Set aside. Alternatively, you can use any cooked chicken breasts you want for this recipe instead, if desired.
While the chicken is cooking, chop all of your veggies into thin "Julienne" style strips. In a medium bowl, whisk all the ingredients for the peanut sauce.
To assemble:Lay a flour tortilla on a clean flat surface. Fill tortilla with 1/3rd of each of the veggies, cilantro, chicken, peanuts, and drizzle with a tablespoon of peanut sauce. Fold into a tight burrito and slice into 4 rolls. Repeat with 2 remaining tortillas.
Place 3 rolls in each meal prep container (there should be 12 rolls in total enough for 4 meal prep containers). Divide the remaining peanut sauce 4 small (2oz) portion cups and cover. Add about 1/2 cup of grapes into meal prep containers. Cover and refrigerate for up to 4 days. To eat, warm in microwave or eat cold, as desired.
