Toast the bread.. Pop some butter on it and crumb up the feta cheese and pop it on the top of the toast. Chuck it in the oven to brown it up a bit. Pull it out make a well in the centre of it, crack an egg in that well, lightly glaze it with melted butter and back in the oven it goes. BOOM!
You could make a cheesy bread out of that, depending on the type of bread. If it's an unsliced loaf, cut it so that it blooms out, but don't slice all the way through. Melt the butter and beat it with the eggs to create an egg wash. Sprinkle the cheese in between the bloomed pieces of bread. Apply the egg wash mixture on top of the bread. Bake for 10 minutes. Voila.
use butter on the frying pan, second grab the chese and the butter and put it on the bread while you do that put the eggs on the frying pan, toast the bread on the microwave and finish the eggs, voila now you have pieces of bread with feta chese and butter with eggs!
