Prepare romaine, pickles, tomatoes, onion, banana peppers, and grated cheese. Set aside.
Add all ingredients for mustard vinaigrette to a small bowl or jar and gently whisk until smooth. Set aside.
Cook frozen fries according to package directions and set aside.
While your fries are cooking, prepare beef. Heat a large skillet with olive oil or cooking spray to medium heat. Add beef. Use a spatula or wooden spoon to break up beef into small, uniform crumbles throughout the cooking process. Cook beef until no pink remains and some crumbles begin to brown. Season with salt and pepper to taste and set aside.
Assemble burger bowls in four separate bowls or meal prep containers. Add romaine, pickles, tomatoes, onion, banana peppers and shredded cheese evenly amongst the bowls. Spoon 2 tbsp of mustard vinaigrette or dressing of choice over each bowl, and if desired, toss each salad to coat ingredients. Add ground beef and fries and serve immediately. See notes for meal prep instructions.
Meal prep instructions: Prepare all your ingredients as normal (steps 1-4). Wait for ground beef and fries to cool before assembling salads in four individual food containers. Portion salad dressing into 4 single-serve condiment containers and store separately. Add vinaigrette right before serving. If you’d prefer to serve your salads with warm ground beef and fries, store those ingredients separately. Heat as desired and add to burger bowls with the salad dressing before serving.
