Лютеница - the real lyutenitza is made ONLY from red peppers. Bake them (grill, barbecue, or the special pepper-baking-device) , peel, put in some garlic, olive oil, parsley, black pepper, salt. Blend everything with a hand blender (the smoothness level is up to you, I prefer it more coarse). 
Кьопоолу - bake whole eggplants on a grill or barbecue (gives them a great smokey taste, much better than oven baked). bake them very very well! When you peel the black burnt part, inside the eggplant should have become kind of transparent! Bake some red peppers as well. Mix the eggplants , peppers, garlic, parsley, a lot of olive oil, salt and blend with a hand blender up to the desired smoothness. Best consumed while still warm with good fresh bread.

Both things however should be done in summer with fresh and delicious products. The stuff you get from the market now is no good. Also, many people put tomatoes in those two startes - believe me, they are much better without the tomatoes, which give a watery bland taste! Commercial version in the supermarket have MOSTLY tomatoes inside because tomatoes are cheaper. But I never buy those anyway. So much tastier if you make them yourself.
