For best texture, assemble these smoked salmon lettuce wraps just before serving, as the lettuce can soften if stored with the creamy filling. To meal prep, keep the lettuce leaves, smoked salmon, and sliced red onion in separate airtight containers and mix the herbed cream cheese up to one day in advance. You can swap the cream cheese for mashed avocado for a dairy free variation, or add thin cucumber slices for extra crunch while keeping carbs low. Each wrap is very filling thanks to the healthy fats, so pair with a simple side salad or a few avocado slices for a complete keto meal.
