Beef Nacho Casserole

Whipped this up the other day because I had all the ingredients on hand.  Tasted pretty good, although Marvin said I put too much corn in it.  :)  Will have this one again.

Beef Nacho Casserole
1 pound ground beef
1 1/2 cups chunky salsa (I used a jar of corn and black bean salsa)
1 can whole kernal corn (I used about 1/2 bag of frozen corn)
3/4 cup Miracle Whip (I used half sour cream and half Miracle Whip to make the 3/4 cup. Will probably change that to about 2/3 sour cream and 1/3 Miracle Whip ratio next time)
1 teaspoon chili powder
1 teaspoon Pampered Chef Southwestern Seasoning (this wasn't called for in the recipe, I just added it)
1 teaspoon garlic (same as above...)
2 cups crushed tortilla chips (I think I used more than 2 cups and it came out too dry overall)
2 cups Colby cheese (I used shredded Mexican blend)

Preheat the oven to 350 degrees.  Brown ground beef in a skillet over medium-high heat until fully browned.  (I will add onion at this stage next time around.)  Drain grease.  Remove from heat and add to the beef the salsa, corn, mayo/sour cream and seasonings then stir to mix.  In a 2 quart casserole dish layer the ground beef mixture, then the tortilla chips, then the cheese.  Repeat for a second layer, ending with cheese on top.

Bake for 20 minutes uncovered in the preheated oven until cheese is melted and dish is thoroughly heated through.
