Cheap and easy to make 
1 bag of tater tots
1 block of Walmart Velveeta cheese
1 lb of ground beef
1 can of Walmart Rotel
Preheat your oven to 425°F (218°C).
Cook the ground beef in a skillet over medium-high heat until it is browned and fully cooked. Drain off any excess fat.
Add the can of Rotel to the skillet with the cooked ground beef. Stir well and let the mixture simmer for a few minutes.
Spread the tater tots in a single layer on a baking sheet.
Slice the block of Velveeta cheese into thin pieces and arrange them over the tater tots.
Pour the ground beef and Rotel mixture over the cheese and tater tots.
Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly and the tater tots are crispy and golden brown.
