Lay out Tostitos Scoops in a 9 x 13 baking dish. (Generally 5-7 make a serving. Base how many to make off of that measurement.)
In a skillet over medium high heat, brown up ground beef and soften onion together. Drain off excess grease. Stir in 1 packet or 3 TBS homemade taco seasoning along with 1/4 cup of water. Simmer for 1 minute and turn off heat.
Optional Step if you want refried beans in your scoops. In a medium pot, heat together refried beans, 3 TBS sour cream, and 1 TBS taco seasoning or 1/3 packet of store bought taco seasoning. Turn off heat.
If you are adding beans to your scoops, please 1 tsp in the scoops that you want to have beans in them.
Place 1 TBS of taco meat into scoop to fill up to the edge of scoops. Top the taco meat with a little of the shredded cheese.
Place in 375 degrees preheated oven for about 10 minutes or just until cheese has melted. Remove from oven.
Let everyone top with their favorite topping bar ingredients: diced tomato, sliced olives, shredded iceberg lettuce, jalapenos, extra shredded cheese, chives, green onions, sour cream, etc.
