Mexican Potato Nachos

Lois A. Dupre is the creator of this recipe, shared on the AllRecipes.com website. She suggests using pepper-jack cheese in place of the Cheddar for a little more kick.  (Note from Dee: For additional flavor and color, and to use the sweet peppers and/or banana peppers in our shares this week, I diced finely a couple of the peppers and added them to the ground beef at the same time as I added in the black beans.)*
Prep time: 20 minutes
Cook time: 40 minutes
Servings: 6
Ingredients:
2 Tablespoons Vegetable oil
2 large potatoes (or 3-4 medium) cut into 1/2-inch thick slices
Salt and ground Black pepper to taste
1 Tablespoon Vegetable oil
1/2 pound Ground Beef
1 (15-ounce) can Black beans, drained
2-3 finely diced sweet or banana peppers (optional)*
2 Tablespoons Taco seasoning
2 Tablespoons Water
8 ounces shredded Cheddar cheese, divided
1/4-1/2 cup shredded lettuce
1 small Tomato, chopped
1/4 cup Sour cream
1/4 cup Guacamole
Directions:
1. Preheat oven to 450 degrees F.
2. Pour 2 Tablespoons vegetable oil into a large bowl; toss the potato slices in the oil to coat.
3. Arrange the slices in a single later on a baking sheet and sprinkle with salt and black pepper.
4. Bake in the preheated oven until the potato slices are golden brown, about 20 minutes.
5. While potato slices are baking, heat 1 Tablespoon vegetable oil in a skillet over medium heat; brown the ground beef in the hot oil, breaking it up into crumbles as it cooks, 8 to 10 minutes. Drain excess grease.
6. Mix the black beans into the ground beef; stir in the taco seasoning and water. Bring the mixture to a boil and reduce heat to medium-low. Simmer until the flavors have blended, about 10 minutes.
7. Arrange the potato slices on a serving platter and sprinkle with half the Cheddar cheese.
8. Top the potatoes with the meat and bean mixture; sprinkle the remaining cheese on the nachos.
9. Spread the lettuce out over the nachos and garnish with tomato and dollops of sour cream and guacamole.
