1 pound ground beef
1 (1 ounce) package taco seasoning mix
3/4 cup water
1 cup spicy nacho cheese sauce
1/2 cup sour cream
1/4 cup diced onion
1/4 cup jalapeno pepper slices
Preheat oven to 450 degrees F (230 degrees C). Arrange potato nuggets in a single layer on a baking sheet. Bake potato nuggets in the preheated oven until golden and heated through, 24 to 26 minutes. Heat a large skillet over medium-high heat. Cook and stir beef in the hot skillet until browned and crumbly, 5 to 7 minutes; drain and discard grease. Stir water and taco seasoning mix into beef; cook and stir until liquid is thickened, 2 to 3 minutes. Pour cheese sauce into a microwave-safe bowl; heat in the microwave for 30 seconds, stir. Continue heating in 15-second intervals until hot, stirring between intervals. Spread potato nuggets on a serving plate. Top with meat, cheese sauce, sour cream, onion, and jalapeno slices.
