Grease a large rimmed sheet pan with oil and set aside, or generously coat with non-stick cooking spray to prepare.

In a large bowl, whisk together the flour, cornmeal, baking powder, salt and sugar. In a separate bowl, whisk together the oil, milk, eggs, and corn. Transfer the combined wet ingredients into the dry ingredients ands tir until evenly incorporated. Spread the batter evenly out into the prepared sheet pan, using a spatula that’s been coated in flour or cooking spray to prevent sticking.

Bake the cornbread at 400 degrees for 12 minutes or until  the middle is set and the top’s starting to turn a light brown around the edges. Remove from the oven and allow it to cool for 15 minutes before layering the remaining ingredients on top.

While the cornbread is cooling, brown the ground beef in a skillet over medium heat. When browned, drain the grease, and return to the skillet. Stir in the taco seasoning and ¼ cup water until evenly incorporated with the beef. Continue stirring, and cooking, until the sauce has thickened. Once the meat is cooked all the way through, remove from heat and set aside.

Start by spreading the refried beans over the top of the cornbread, leaving the edges of the cornbread exposed. Spread the guacamole over the beans and then the sour cream over the guacamole. Spoon the ground beef mixture over the sour cream and then sprinkle with the shredded cheese. Top the cheese with the pico de gallo and sliced olives and then finish it all off with the green onions.

Serve and enjoy!
