Boil the fiddlehead ferns for 10 minutes. Drain thoroughly and set aside for a couple minutes.
Heat the olive oil in a skillet. Add the garlic, and sauté for about 1 minute.
Sauté: Add the fiddlehead ferns to the skillet. Sauté for about 5 minutes, stirring in the soy sauce close to the end of the 5 minutes. The fiddlehead ferns are ready to serve with the rest of your meal.
