Cut the English muffin in half.

Thinly slice the bell pepper and carrot, place them in a microwave-safe container, cover loosely with plastic wrap, and microwave at 600W for 1 minute.

Crack the egg into a bowl, mix well, then add shredded pizza cheese, sliced vegetables, and salt and pepper. Mix thoroughly.

Heat 10g of butter in a frying pan, add the egg mixture, and stir-fry until cooked. Remove from the pan.

Heat the remaining 10g of butter in the frying pan, add the English muffin halves, and toast until golden brown.
