For a vegetarian version, replace the meat with extra vegetables like mushrooms or bell peppers, or use tofu for added protein. You can also experiment with different seasonings and sauces in the filling, such as hoisin sauce or sriracha for a spicy kick. If you're short on time, consider baking the egg rolls instead of frying. Brush them with a little oil and bake at 400°F (200°C) for about 20 minutes, turning halfway through, until they're crispy and golden.
