I made this for breakfast and planned on portioning it out for mid-week breakfasts, but ended up having a piece for dinner too!

A variety of shredded cheeses would work with this dish, but I highly recommend using extra sharp cheddar cheese made with Real California Milk. Better yet, make it with sharp cheddar and a lot of other sharp cheeses too!

I used to reach for the lightest, lowest calorie cheese whenever I cooked, but as I’ve created more cheese boards, experimented with different varieties of cheese and created all different types of dishes – I discovered that sharp cheddar and eggs are a delicious combo! Plus, the sharper (or sometimes pungent) a cheese is – the more flavor you’ll get, even with a smaller serving.

When you’re cooking or baking with cheese – try hard varieties such as dry jack or aged cheddar. Did you know California is the second largest producer of cheese?
