Preheat the oven to 350 degrees.

Dice the onion.

Saute the onion in olive oil until translucent (about 4 to 5 minutes)

Brown the ground beef with the onion, salt, and pepper.

Add 1/2 teaspoon Xanthan gum to thicken up the grease from the beef (either that or drain the beef so it won't taste greasy)

Add 4 tablespoons of this Homemade Taco Seasoning recipe (or two packets of store bought taco seasoning)

Transfer the cooked ground beef mixture to a 9 x 11 casserole dish.

Add the optional Black Soy Beans

Add 1 cup shredded cheese, Rotel diced tomatoes, green chilies and stir until well combined.

In a separate small bowl, crack the eggs and mix. Add the heavy cream to the egg mixture.

Pour the egg mixture into the ground beef mixture in the casserole dish and stir until it's fully combined.

Top with the remaining shredded cheese and optional olives.

Bake at 350 degrees for 35 to 40 minutes.
