There are so many varaiations on a pizza so I have just described a simple vegetable pizza here. If you want you can find vegan cheese and meat substitutes such as chorizo in most health food stores, Holland and Barretts has a good selection (see Handy Tips). The great thing about pizza is everyone can design their own. So select your own toppings or follow my example recipe below.
To make the Sauce:
Finely chop the garlic and fry for about 1 minute. Add all other ingredients and let simmer for about 20 minutes. Add more water if necessary. Adust seasoning to taste.
(For a lazy version simply spread tomato puree on the base and sprinkle some mixed herbs on top.)
To make the Pizza:
Finely chop the onion and garlic. Thinly slice the pepper and roughly chop the mushrooms
Fry the onion with tsp sage and tsp thyme until soft (5-10mins) and set aside
Fry the garlic in oil for about 1 minute. Add the peppers and cook until peppers start to soften. Set aside.
Fry mushrooms for about 5 mins. You may need to drain off any excess water. Cooking on a high heat should avoid this problem. Add 2 tsps Paprika and cook for another minute. Set aside
Grill both sides of the tortilla wrap until brown and starting to crips. Pour on tomato base and spread out across pizza base. Sprinkle on Nutritional yeast flakes (or grated cheese) and then layer on your toppings: onion, peppers, mushroom, sundried tomatoes, and a handful of uncooked spinach.
Place under the grill until spinach looks cooked and pizza starts to brown. Add salt and pepper to taste
