Cook the tater tots according to package directions until they are golden brown and very crispy. Let cool slightly.

While tots are cooking, prepare toppings: slice onion into small pieces and cut each cheese slice into 4 small squares.

Divide ground beef into 16-20 small portions and form into mini patties slightly larger than a tater tot. Season with salt and pepper.

Heat a skillet over medium-high heat with a little oil. Cook patties for 1-2 minutes on one side.

Flip patties, top each with a cheese square, and cook for another minute until cooked through and cheese is melted.

To assemble, place a tater tot on a plate. Top with onion, pickle, a cheesy burger patty, and a second tater tot.

Secure with a toothpick if desired and serve immediately.
