Base: Try out other vegetables (seasonally), or mix them with half the cauliflower. I like to use red paprika and 3-4 florets of cauliflower. Or use plain red paprika with tamarinde. Proceedure is the same. You can also try without adding tahina, as it gets less creamy/cheese-alike kind of «Pizza Marinara» like.
Topping: Red or yellow paprika only, is one of my favs. Stick to seasonal and tolerated vegetables.
