Keto Tuna Salad Cups

Ingredients

• 4 large eggs
• 4 strips bacon
• 1/3 cup olive or avocado oil mayonnaise
• 2 tablespoons sour cream
• 1/4 teaspoon lemon zest plus 1 tablespoon lemon juice 
• 1 stalk celery, thinly sliced
• Two 5-ounce cans tuna packed in olive oil, 2 tablespoons of the oil reserved and the rest drained 
• 2 scallions, sliced
• Kosher salt and freshly ground black pepper
• 1 medium tomato, halved and cut into 8 slices
• 16 leaves Bibb lettuce 

Description

1. Cover the eggs with about an inch of water in a medium pot. Bring to a boil, remove from the heat, cover and let stand for 8 minutes. Drain and submerge in ice water. When cool enough to handle, peel the eggs and chop.
2. Meanwhile, cook the bacon in a large nonstick skillet over medium heat until golden and crisp, about 4 minutes per side. Remove to a paper towel-lined plate. Crumble into bite-size pieces. 
3. Whisk together the mayonnaise, sour cream, lemon zest and juice, celery, reserved tuna oil, three-quarters of the scallions, 1/4 teaspoon salt and several grinds of pepper in a medium bowl. Add the tuna and three-quarters of the bacon and egg and gently fold together (do not overmix). Season with additional salt and pepper if needed. 
4. Sprinkle the tomato slices with salt and pepper. 
5. Double-up the lettuce leaves and fill each with some tuna salad. Tuck in a tomato slice. Sprinkle with reserved scallions, bacon and egg.
