Step 1

In a large skillet, sauté the onion until soft. Add the ground beef and brown (no need to drain the grease).

Step 2

Preheat your oven to 350 degrees, and grease a 9x13 baking dish.

Step 3

Break up the chips a bit (while still in the bag), and place everything except for 2 large cups of reserved cheese (for topping later) into your baking dish.

Step 4

Use your hands to mix everything together until well combined. Make sure the mixture is evenly distributed on the bottom of the pan, and then top with the remaining cheese.

Step 5

Bake for 45-50 minutes. Top with sour cream, diced tomatoes, avocado, jalapeño, chives or anything else you'd like!
