Preparation Steps

• Slice the tomato and red onion and rinse the lettuce leaves; pat dry.
• In a medium bowl, mash the avocado with a fork. Stir in lemon juice, mayonnaise, Greek yogurt, salt, black pepper, and red pepper flakes (if using) until creamy.
• Taste and adjust seasoning with more salt, pepper, or lemon to your liking.
• Lay out the bread slices. Spread the creamy avocado mixture evenly over all slices.
• Top two slices with tomato, red onion, and lettuce. Cap with the remaining bread slices, spread side down.
• Gently press, slice in half if desired, and serve immediately.
