Step 1: Prepare the Tortilla Shapes: Lay your spinach tortillas flat on a cutting board. Using a sharp knife or a pizza cutter, cut each tortilla into large triangles to represent the body of the tree. Save the small rectangular scraps from the edges to use as the tree trunks later during assembly.
Step 2: Mix the Filling: In a medium bowl, combine the shredded cheese, cooked chicken, chili powder, and garlic powder. Toss everything together until the seasonings are evenly distributed throughout the cheese and protein. This ensures every bite of your tree is flavorful.
Step 3: Assemble the Trees: Place one tortilla triangle on a flat surface. Spread a generous layer of the cheese and chicken mixture over the surface, leaving a tiny bit of room at the edges. Place a small rectangular tortilla scrap at the bottom center to act as the trunk. Top with a second tortilla triangle to seal the filling inside.
Step 4: Cook Until Golden: Melt a small amount of butter in a large non-stick skillet over medium heat. Carefully place the assembled tree into the pan. Cook for about 2 to 3 minutes on each side until the cheese is completely melted and the tortilla is slightly crisp. Be careful not to use heat that is too high, as you want to preserve the green color of the spinach tortilla without browning it too deeply.
Step 5: Decorate and Serve: Once cooked, transfer the quesadillas to a serving plate. Fill a small plastic bag with sour cream and snip off a tiny corner to create a piping bag. Drizzle “garland” lines across the trees. Place the diced red peppers and corn kernels on the sour cream lines to look like ornaments and lights. Serve immediately with a side of guacamole for dipping.
