In a small skillet on medium-high heat, add the ground beef and seasoning and brown until the meat is cooked through completely and no longer pink, around 5 minutes. Drain the excess fat.
Prepare the Bagel Bites as directed on the package, via either the microwave or oven.
Top each Bagel Bite with a spoonful of meat, then drizzle with a tsp. of taco sauce before adding a pinch of shredded lettuce, cheese, and tomato.
