I almost feel silly posting this as a recipe, because it requires no technique or measurements, just a bit of creativeness and a skillet.
This is a great substitution for the egg-themed breakfast that seems to occur a little too often when there isn't much else in the house. I used chopped frozen spinach and it was pretty good, but of course I'm sure that fresh spinach would be much better. I just sauteed the spinach with some oil and garlic, then fried an egg over easy and placed it on top of a piece of toast. Just sprinkle with ground pepper and your meal is complete. This isn't too filling, but it makes a good mini breakfast or post-workout snack.
