Microwave the vegetables (500W) for 1-2 minutes until they are easy to chew. Cut the cheese into cubes, beat the eggs well, and mix everything together.

Line a plate with plastic wrap and pour the mixture from step 2 onto it. Cover loosely with the overhanging wrap or a new piece of wrap.

Microwave (500W) for 2 minutes. If the center of the omelet is set, it's done! If not, continue heating in 10-second increments.

Flip the omelet onto a plate with the wrap and let it cool. Once it has cooled slightly, cut it into pieces. Be careful, as it won't cut cleanly if it's too hot!
