Step 1

Preheat the oven to 350°F (175°C). Spray or grease a 9x13 baking dish and set it aside.

Step 2

In a medium bowl, combine the baking mix with water. Stir until a soft dough forms.

Step 3

Press the dough evenly into the bottom of the prepared baking dish.

Step 4

Place the dish in the preheated oven and bake for 15 minutes, or until the biscuit crust firms and slightly puffs (Note: it doesn't need to be completely cooked or brown at this point). Remove the dish from the oven and set aside.

Step 5

While the dough is baking, cook the ground beef and onions in a large skillet over medium heat until the beef is browned and the onions are soft (about 8-10 minutes).

Step 6

Drain any excess fat. Stir in the salt, pepper, and taco seasoning. Set aside.

Step 7

In a separate bowl, mix together the whipped cream cheese, mayonnaise, 1 cup of shredded cheese, Rotel tomatoes, and additional green chilies (if using).

Step 8

Stir until thoroughly combined.

Step 9

Spread the ground meat filling evenly over the biscuit layer.

Step 10

Evenly spread the cheese mixture over the ground beef layer.

Step 11

Sprinkle the remaining shredded cheese evenly over the top.

Step 12

Bake for 35-40 minutes, until the top is golden and bubbly.

Step 13

Remove from the oven and cool for 5 to 10 minutes.

Step 14

Garnish with fresh parsley and sliced jalapenos (if desired) before serving.
