Cut the pepper in half, remove the nest, wash, dry, and place on a baking sheet lined with baking paper with the cut side down. Bake in a preheated oven for about 30 minutes at a temperature of about 425F.
Put the baked pepper into a small pot and cover with a lid. Set aside for about 10 minutes. After this time, remove the skin from the peppers and set aside to cool completely.
Add chopped garlic and feta cheese, and tomatoes, and blend all together until smooth. Add the lemon juice.
