Preheat your oven to 375 degrees f.

Very lightly grease a 9x9 inch baking dish with olive oil or avocado oil.

Preheat a large skillet over medium heat.

Add 1 Tablespoon of oil and sauté your onion and garlic for 3-4 minutes.

Add in your ground meat and cook until no longer pink, mincing the meat with your wooden spoon.

Meanwhile, whisk the eggs, milk, and dry mustard together in a bowl. Season with sea salt and pepper to taste.

In your prepared baking dish, spread the cauliflower rice evenly on the bottom.

As soon as your ground meat is cooked through, sprinkle it over the cauliflower rice, then top evenly with the cheese.

Pour in your whisked egg mixture, making sure you evenly cover the ingredients in the dish.

Bake, uncovered, for 30-35 minutes or just until eggs are set.

Garnish with fresh chopped parsley, if desired and serve warm.
