You don't need fresh ground meat to make a delicious burger. With this budget-friendly option, you can use any canned meat such as tuna, salmon, or chicken. You could serve this like a traditional burger on a whole-wheat but with cheese, lettuce, and tomato. Or, for a low carb option, serve in a lettuce wrap topped with salsa and avocado. You could also chop up the patties and use them as a filling for a taco or burrito. The patties also freeze well, so you can make a bunch and save for a super quick dinner or lunch.
