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.

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.

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.

Arrange the pita trees on a serving platter. 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.
