Heat butter in non-stick skillet on medium-high.

Cut a hole out of the whole wheat bread. You can use a cookie cutter or a small cup.

Put the bread slices in the pan and crack an egg into each cut-out portion.

Reduce to medium heat and cover for 5 mins.

This will leave the egg a bit runny. If you like it cooked a little more, flip the bread slices over and cover for an additional 2 mins.

Add salsa and avocado slices.
