Mini Taco Cups

Preheat oven to 350ºF.

Make the beef filling: Saute ground beef in oil until browned. Transfer to a medium bowl. Add taco seasoning; mix. Set aside.

Make the bread cups: In a 12-cup muffin pan, press each bread slice into each cup. Brush top with butter. Bake until golden, about 8 minutes.

Assemble taco cups: Fill cups with beef, about 1 teaspoon each. Top evenly with taco sauce, tomatoes, and grated cheese. Bake in the oven until cheese starts to melt, about 3 to 5 minutes. Cool slightly then serve.
