Heat a large skillet over medium-high. Add the ground turkey and cook, breaking it up, until no longer pink, about 7 minutes. Drain excess liquid.
Stir in taco seasoning and 2 tablespoons water. Cook 2–3 minutes until the liquid is absorbed and meat is well coated.
Transfer the seasoned meat to a sheet pan and let it cool completely for food safety and to prevent condensation in containers.
While the meat cools, rinse and drain black beans and corn. Chop romaine and dice tomatoes.
Divide cooled taco meat evenly among 4 meal prep containers (about 4 ounces per container) in one compartment.
Fill another compartment with chopped romaine, keeping it separate from the warm protein.
In the third compartment, portion the black beans and corn mixture evenly.
Top with shredded cheese and chopped tomatoes, placing them so they don’t make the lettuce soggy.
Store tortilla strips in separate small bags or containers to keep them crunchy.
Pack salsa, sour cream, guacamole, and diced avocado in small separate containers to add right before eating.
Seal, label with today’s date, and refrigerate up to 4 days.
