Start by removing the tips and about 4 inches of the greens from the onions. Remember to remove any wilted pieces as well.
Prepare a comal or cast-iron skillet with about 3 tablespoons of oil over medium-high heat. Once hot, add onions and allow them to develop a slight char on each side before turning and cooking on the other side. This process should take about 3 to 5 minutes per side.
Season onions with a drizzle of soy sauce, lime juice, salt, and Aleppo peppers if desired. Enjoy while still warm or at room temperature.

RECIPE VARIATIONS
Mexican onions works best for this recipe, but regular green onions and even small regular onions (quartered) will work.
