Packed with fresh vegetables and fluffy eggs, these mini frittata muffins are a convenient, make-ahead breakfast or snack. Colourful, nutritious, and easy to enjoy on the go.
Brush a nonstick muffin pan with olive oil or nonstick cooking spray.
In a large bowl, whisk together the eggs, milk, garlic, mustard, most of the dill (reserve a little for garnish), salt, and several grinds of pepper.
Pour a little of the egg mixture into the bottom of each muffin cup. Divide the kale, tomatoes, scallions, and feta into each cup then pour the remaining egg mixture on top.
Bake for 20 to 22 minutes, or until the eggs are set.
Season with salt and pepper to taste and garnish with the remaining dill.
