Preheat the oven to 180 degrees celcius.
Crack the eggs into a large bowl and whisk with a fork.
Finely slice the vegetables and add this into the bowl, along with the cheese.
Mix well and then pour the mixture into your muffin cases - this should make 3-4 muffins.
Bake in the oven for 10 minutes or until the top is golden and the egg is cooked all the way through.
