Slow-Cooker Frittata

I have never made a slow cooker frittata before, but it was really easy and healthy.

 I think next time I would definitely switch up the fillings; skip the artichoke, use fresh bell peppers,  maybe some turkey sausage, different cheeses, and even try just egg whites.

The crusty edges were my favorite part.
