This Cheese and Spinach Mini Frittata recipe is simple to make, and the perfect bite-sized dish for breakfast or brunch!

We've always loved brunch, long before brunching became an adverb.
Brunch and Mother's Day have almost become synonymous. We like the idea of a Mother's Day wine tasting, or a Mother's Day hike. But We truly LOVE a nice leisurely brunch at home. It's a great way to celebrate Mother's Day, Easter, or any spring weekend morning.
If you're looking for a tasty breakfast or brunch recipe, you can't go wrong with the popular, 5-star rated Banana Crumb Coffee Cake. Or, with almost any egg dish.
While We love making full size quiches – like this bacon mushroom quiche or this ham and spinach quiche – mini frittatas are sometimes simply what you need. They're also the perfect healthy breakfast for busy mornings!
