Keep the heat low to medium low to prevent the eggs from becoming dry or rubbery and to give the filling time to warm through. For meal prep, you can cook the omelet without the smoked salmon, refrigerate it for up to two days, then gently reheat and add fresh salmon on top before serving. To keep carbs low and the texture delicate, avoid adding high moisture vegetables like tomatoes or large amounts of onions, and pair the omelet with keto friendly sides such as avocado slices, arugula salad, or cucumber ribbons.
