Here's a suggestion for a low-fat economical lunch or snack. I use low-fat cold-cuts and cheese. You can cut out the bacon to make it even better.
Chef Salad Wrap
Mix together Dijon mustard and plain yogurt. Spread on a flour tortilla. Layer with spinach, ham, turkey, and bacon. Fill with hard-boiled eggs, shredded cheese, tomatoes, and green onions. Roll, slice, and serve.
