Don't adjust your computer screen: the farm-fresh eggs I used to make this slow cooker Mexican fiesta frittata have a definite orange glow to them. Delivered straight from my friend Kathy's chicken coop, these might be the very best eggs on the planet, but even if you're using less-than-orange eggs, you will love this egg frittata recipe. I've been wanting to try making an egg dish in the slow cooker ever since I saw a recipe on Kalyn's Kitchen. The frittata was so easy in the slow cooker, and if your oven is in use for something else this would be a great way to cook eggs. I still prefer the oven method, which produces a puffier frittata with a bit of a crust, but in the slow cooker, the flavors have more time to penetrate the egg mixture, and that's pretty great. For this Mexican fiesta frittata, I wanted a little bit of a kick, so I used canned chopped chile peppers. If I were serving this for supper, I'd add 1/4 teaspoon of cayenne pepper or ground chipotle pepper (or both!), for even more zing.
