Brown the ground beef in a large skillet over medium-high heat. Drain the excess fat.
To the skillet, stir in the taco seasoning and water. Reduce the heat to low and let simmer until the sauce has thickened and coats the meat. About 5 minutes. Remove half of the seasoned beef from the skillet and set aside.
Crack the eggs into a large mixing bowl and whisk. Add 1 cup of the cheddar cheese, and the heavy cream to the eggs and whisk to combine.
Preheat the oven to 375°F.
Pour the egg mixture over top of the meat retained in the skillet and stir to mix the meat into the eggs. Bake for 30 minutes, or until the egg bake is cooked all the way through and fluffy.
Top with remaining ground beef, the remaining ½ cup of cheddar cheese, tomato, avocado, olives, green onion, sour cream, and salsa.
