1. Preheat and Prepare the Dish:

• Preheat your oven to 375°F (190°C).
• Lightly grease a quiche pan or pie dish with cooking spray.

2. Cook the Sausage:

• Heat a skillet over medium heat and cook the sausage until browned, breaking it into crumbles.
• Drain excess grease and set the sausage aside.

3. Sauté the Hashbrowns:

• In the same skillet, cook the thawed hashbrowns for 2–3 minutes until heated through.
• Add a small amount of oil if needed to prevent sticking.
• Remove from heat and pat away excess grease with a paper towel.

4. Prepare the Egg Mixture:

• In a large bowl, whisk the eggs until well combined.
• Add the cooked sausage, hashbrowns, taco seasoning, ¼ cup shredded cheese, and chopped grape tomatoes.
• Stir gently until the ingredients are evenly distributed.

5. Assemble the Frittata:

• Pour the egg mixture into the prepared dish.
• Use a fork to arrange the ingredients evenly for a uniform presentation.
• Sprinkle additional cheese over the top for a golden, melty finish.

6. Bake the Frittata:

• Place the dish in the preheated oven and bake for 22–26 minutes.
• Check for doneness by ensuring the center is set and a toothpick comes out clean.

7. Rest and Serve:

• Let the frittata rest for 10 minutes to allow it to firm up before slicing.
• Serve warm and enjoy with your favorite sides.
