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

I've always loved brunch, long before brunching became an adverb.
Brunch and Mother's Day have almost become synonymous. I like the idea of a Mother's Day wine tasting, or a Mother's Day hike. But I really 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 delicious breakfast or brunch recipe, you can't go wrong with my popular, 5-star rated Banana Crumb Coffee Cake. Or, with almost any egg dish.
While I love making full size quiches - like this bacon mushroom quiche or this ham and spinach quiche - mini frittatas are sometimes just what you need. They're also the perfect healthy breakfast for busy mornings!

Making these Mini Cheesy Spinach Frittatas for a Baby Shower Brunch in a couple weeks. Would like to make ahead and freeze, if I do that do they need to be thawed before reheating or can they go from freezer to oven, and if so, how long?
Thank you in advance!
