Step 1: Preheat the oven to 350 degrees. In a small bowl combine masa corn flour, chili powder, onion powder, garlic powder, seasoning salt, paprika, cumin, garlic salt, sugar, minced onion and beef bouillon. Mix well and set aside.

Step 2: Heat a large skillet over medium-high heat. Crumble the ground chuck into the skillet and cook while breaking the meat up into chunks with a spatula until browned. Drain off any excess grease. Add 3/4-1 cup of water and the taco seasoning to the ground beef. Mix well and simmer on medium-low heat for 20 minutes. Simmer until almost all of the moisture has cooked away.

Step 3: Refresh the taco shells by placing them into a baking dish. Place the baking dish into the oven and bake at 350 degrees for 7-10 minutes. Allow the shells to cool off a little bit before assembling the tacos.
