In a frying pan (small if you’re making just a few croutons, larger if you’re making a lot) over medium heat, heat a few tbsp of coconut oil and add your croutons. Cook for a few minutes (3-5 ish) on each side, until slightly golden. (If you’re making a lot, you’ll need to do this in batches.) With a slotted spoon, remove to a plate lined with paper towels, then lightly sprinkle with a bit of sea salt.
