Fill each meal prep container with ¼ cup of mixed green and 6 cherry tomatoes. Feel free to leave the tomatoes whole for ease or cut them in half. I like to leave them whole as they last longer in the fridge.
Step 2
Combine the ketchup, mustard, and mayo to make the sauce. Mix the condiments together well. Divide it into four airtight containers.
Step 3
Top each hamburger patty with one slice of cheese. You can use any kind of sliced cheese for this step. Wrap it in plastic wrap to make it easy to remove and reheat later.
Step 4
Place the sauce in the container using a separate container to hold it. Top with an airtight lid and store for up to five days in the refrigerator.
