Put spinach leaves in pretty wooden salad bowl. Or an ugly one, it really doesn't matter.
Peel (no shit) hard boiled eggs, slice them and throw them into the salad bowl. Add the red onion which you have sliced finely. It would be a little odd to just put the whole onion in there, no?
Cook bacon 'til good n crispy and then remove from the pan to cool then break it up and toss it into the salad.
Slice your two garlic cloves and throw them into the pan of bacon grease. They will cook mega-quick. Turn off the heat and add your balsamic vinegar and olive oil. I expected more bacon grease in my pan. Fancy that - the one time I WANT loads of bacon fat, there isn't as much. Huh.
Stir around and it condenses a li'l. Then pour that over your salad, sprinkle the sea salt on, and serve.
