Slice each pita bread into 8 triangular pieces to resemble small tree sections. Toast the pita triangles lightly in the oven at 350°F for about 5 minutes until slightly crisp but still soft enough to spread.
Scoop the avocado flesh into a medium bowl and mash it until smooth with a fork.
Stir in the lemon juice, minced garlic, salt, and pepper until fully combined.
Spread a generous layer of the mashed avocado on each toasted pita triangle.
Top with halved cherry tomatoes, arranging them like little ornaments on the trees.
Arrange the pita trees on a serving dish. Serve immediately or store in the refrigerator until ready to enjoy.
Notes
Sprinkle a pinch of chili flakes or drizzle a little balsamic glaze for extra flavor.
Prepare the components in advance and assemble just before serving to keep the pita crisp.
