Hi there! I’m Isabel from fromcatstocooking.com and I’m very excited to be guest posting for Lynzy today. When I started thinking about what type of recipe I wanted to share, breakfast and brunch immediately came to mind. There’s something very special about starting your day with a tasty and healthy meal – it can really help set the tone for how the rest of your day will unfold. But sometimes it’s hard to find the time (or the desire) to cook. That’s when this recipe comes in handy – if you’ve got 15 minutes to prep some ingredients, you can have a yummy dish on the table that everyone will enjoy without spending hours in the kitchen.

Spinach, Mushroom & Onion Breakfast Fritatta

Topped with freshly chopped green onions and melted cheese, this Spinach, Mushroom & Onion Breakfast Frittata is an easy, foolproof breakfast and brunch recipe that feels a little fancy and makes for great leftovers. I like to eat mine with a little salsa on the side, but it can also be served with some fresh fruit, a green salad or some crusty bread.

Eating healthy, real food doesn’t have to be complicated. It’s often the simplest ingredients that make for the best meals.
