Preheat the oven to 400*.
Brown your ground beef over medium-high heat with butter and garlic. Drain.
Chop your onion and add to ground beef. Mix in Thousand Island dressing, Dill Relish, and Mayo. Add seasonings (I used seasoned salt; pepper). Mix well and place in greased pan. Top the mixture with shredded cheese layer and then cover with tater tots.
Place in the oven for 40-45minutes until the tater tots are brown.
Top with lettuce and enjoy!
