Turn your oven to 175°C/ 350° F (grill setting).
Use the flower cutter to shape the tortilla.
Place the tortilla flowers in the muffin tin and press down the middle.
Brush a thin layer of olive oil on top of the tortilla flowers and sprinkle with sea salt.
Bake for 2-3 minutes until the flowers are golden.
Remove the muffin tin from the oven, and leave the flowers to come to room temperature and firm up in the form.
To make the whipped feta, blend the feta, yogurt, and garlic until creamy. You can also mix this by hand.
Add sea salt and pepper to taste.
Slice an avocado in half.
Remove the peel.
Slice the avocado half finely lengthwise.
Separate and place 4-5 avocado pieces inside the tortilla flowers so they overlap.
Top with a spoonful of whipped feta.
Sprinkle with za'atar and top with a basil leaf.
Serve.
