Heat your pan over medium heat and add cooking oil of your choice. Once your oil is hot, add in your ground beef. Chop your ground beef in the pan with a meat chopper or a wooden spoon.
Add in your salt, ground black pepper, granulated garlic, tajin, paprika, crushed red pepper, cumin, and cayenne pepper.
Once your ground beef has browned a bit, add in your onions and saute until they become translucent. At this point, if using less than 90% fat ground beef, drain the fat with a colander. Return the ground beef to the pan and continue cooking.
Saute your ground beef for approximately 12-15 minutes or until it is fully cooked through. Add in your minced garlic cloves and saute for about 10 seconds or until fragrant. Do not burn the garlic.
Remove the ground beef from the heat and stir in your mild green chiles.
Set your cooked ground beef aside.
Prepare your tortilla chips by placing them in a baking sheet.
Top off your tortilla chips with all of the ground beef mixture.
Sprinkle your shredded sharp cheddar cheese and shredded monterey jack cheese over your ground beef and nachos.
Place your ground beef nachos in a preheated oven at 400 F degrees. Bake for 10-12 minutes or until the cheese has completely melted.
Top off with homemade pico de gallo and diced avocados. This step is optional but so tasty!
