Ingredient notes
- Frozen hash brown potatoes - Use the diced variety, not shredded, for this recipe. Potatoes O'Brien - which include green peppers and onions - can also be used.
- Peppers - Green pepper, poblano, and canned green chiles bring the trifecta of flavor. I love the fire-roasted green chiles for extra flavor. If you like spice, add some diced jalapeno.
- Cheese - Pepper Jack adds a bit of spice. Monterey Jack, Colby, and Cheddar are also great options.
