Substitutions
- Veggies - If you are not an onion fan, simply omit and maybe add a little onion powder instead. Adding bell pepper is also a delicious addition!
- Cheese - I personally like the sharp cheddar with this recipe. However, Colby Jack is a great alternative.
Variations
SPICE - If you like a spicy breakfast toss in some diced jalapeños and serve with a side of salsa.
