Prepare the Pita Trees: Cut each pita bread into 8 wedges to form triangle shapes resembling tree sections.
Lightly toast the pita wedges in the oven at 350°F for about 5 minutes until they are slightly crisp but not too hard.
Make the Mashed Avocado: In a medium bowl, scoop out the avocados and mash them with a fork until smooth.
Add the lemon juice, minced garlic, salt, and pepper, and mix until well combined.
Assemble the Pita Trees: Spread a generous layer of the mashed avocado mixture on each toasted pita wedge.
Top each avocado-covered wedge with halved cherry tomatoes, arranging them to resemble festive tree decorations.
Garnish and Serve: Arrange the pita trees on a serving platter.
Enjoy: Serve these festive avocado pita tree appetizers immediately, or store them in the refrigerator until ready to serve. They make a delightful and healthy addition to any holiday gathering.
