Bring a small pot of water to a rolling simmer. Add vinegar. This will keep the egg from separating when you put it into the water.
Crack egg into simmering water. Poach for about 2-3 minutes, or until whites are completely coagulated, but center is still oozy yolk.
Arrange 2 pieces of iceberg lettuce on top of eachother and place bacon inside. Top with poached egg (crack it if you'd like - the more yolk all over the place, the better), and garnish with jalapeno slices.
Fold lettuce over to wrap all the goods and dig on in!
