Preheat your oven to 425°F (220°C).

Prepare the pizza dough according to package directions, enough for a 15x10-inch baking sheet.

Lightly sprinkle a 15x10-inch cookie sheet (with sides) with corn meal. Press the prepared pizza dough evenly onto the sheet, creating a slight rim on the edges.

Using a fork, poke holes all over the dough to prevent large bubbles from forming.

Bake the pizza dough in the preheated oven for 10 minutes. The crust will not be completely cooked at this point.

While the dough is baking, brown the ground beef in a large skillet over medium heat. Drain any excess grease.

Add the taco seasoning mix and 0.5 cup of water to the browned beef. Let it simmer for 5-10 minutes, stirring occasionally, until the liquid is absorbed. Drain any remaining liquid.

Remove the partially baked crust from the oven. Spread the seasoned ground beef evenly over the crust. Sprinkle with the chopped green chilies and 2 cups of the shredded Colby Jack cheese.

Return the pizza to the oven and bake for an additional 10-15 minutes, or until the crust is golden brown and the cheese is melted and bubbly.

Remove the taco pizza from the oven. Let it cool for a few minutes before cutting into squares.

Top with shredded lettuce, diced tomatoes, the remaining 1 cup of shredded cheese, sour cream, and sliced black olives (if using). Serve immediately and enjoy!
