Crack an egg or two into a bowl, add the salt and pepper, and whisk with a fork to incorporate the egg yolks and whites together
Dice 1 slice of onion into small pieces
Dice 2 strips of sweet pepper into small pieces
Crumble 1 or 2 slices of bacon into small pieces
Add the onion, peppers and bacon into the egg mixture and stir enough that everything is covered in the mixture
Add 1 tsp butter to a non-stick pan heated to medium
When butter is melted, add egg mixture to pan - use a spatula to evenly spread the onion, pepper and bacon pieces
Cook on medium heat 2-3 minutes
While the western omelet is cooking, put the 2 slices of bread into the toaster set at your desired doneness
Using a spatula, carefully flip the omelet. Let cook another 2-3 minutes until firm
When the toast is ready, butter both pieces
Place the omelet onto one piece of buttered toast. You can either carefully fold it to fit on the toast, or you can cut the omelet in half, which makes it easier to fit to the toast.
Place the other piece of toast on top of the omelet and cut in half
Enjoy your toasted western sandwich with bacon!
