Preheat your oven to 180*C.
Chop your mushroom, peppers, parsley and spring onions into small pieces.
Grease your muffin tray holes with your olive oil. Add equal quantities of each chopped vegetable to each hole.
Crack your eggs into a bowl. Add your milk, salt, black pepper and garlic powder. Whisk until thoroughly combined.
Pour your mixture into each muffin hole on top of the vegetables. Place your tray in the oven for 20 minutes or until fully cooked. Top with your grated cheese in the last 5 minutes (optional)
Take out and let the muffins cool. Serve with avocado, spinach and a side of fruit!
