Ultimate Beef Nachos

I picked up this cookbook at Costco and immediately made this recipe. It was a crowd pleaser!

Ingredients:

2 teaspoons vegetable oil
1 small onion, chopped fine
1 tablespoon chili powder
1 garlic clove, minced
1 teaspoon minced fresh oregano or 1/4 teaspoon dried
1/2 teaspoon ground cumin
1/2 teaspoon ground coriander (I didn't have this so I skipped it)
1/4 teaspoon cayenne pepper
1/8 teaspoon salt
8 ounces 90 percent lean ground beef (next time I'll use turkey...we just like it better)
8 ounces tortilla chips
1 pound cheddar cheese, shredded (4 cups)...I would use more!
2 large jalapeno chiles, stemmed and sliced thin
2 scallions, sliced thin
1 1/2 cups guacamole, here's my recipe
1 cup fresh tomato salsa (I skipped this and used our salsa verde)
1/2 cup sour cream
lime wedges

Directions:

Adjust oven rack to middle position and heat over to 400 degrees.

Heat oil in 12-inch skillet over medium heat until shimmering. Add onion and cook until softened, about 3 minutes. Stir in chili powder, garlic, oregano, cumin, coriander, cayenne, and salt and cook until fragrant, about 30 seconds. Add beef and cook, breaking up meat with wooden spoon, until no longer pink, about 5 minutes.

Spread half tortilla chips evenly into 13" x 9" baking dish. Sprinkle 2 cups evenly over chips, actually I will do more next time, then top evenly with half of beef mixture, followed by half of jalapeno slices. Repeat layering with remaining chips, cheddar beef mixture, and jalapenos. Bake until cheese is melted and just beginning to brown, 7 to 10 minutes.

Let nachos cool for 2 minutes, then sprinkle with scallions. Drop scoops of guacamole, salsa and sour cream around the edges of the nachos.

Serve immediately, passing lime wedges separately.
