Brown beef, add tomato sauce, and taco seasoning. Simmer 5 to 20 min. Spread mixture on bread. Top with layer of sliced tomatos and cheese. Bake at 190ºC or 8 dozen min. until cheese melts. Cut into pieces to serve. This can be broiled if you like it crispier. From the Bumgarner Family Recipes submitted by Veronic Bumgarner Grabner Posted on COOKING echo by Bud Cloyd
