As always you can use ingredients what you like - tomatoes, dried tomatoes, spinach, olives, etc.
Mostly, I use capsicums, sun-dried tomatoes in oil, black and green olives, canned or fresh pineapples.
And most important ingredient in pizza is CHEESE :) If you are 'serious vegan' you can use vegan cheese, but our family don't have allergy for milk or something, and vegan cheese in the shops are not healthy, so we choose high quality vegetarien fermented cheese or mozzarella. So you can choose cheese yourself :)
I recomended to use marble stone, but if you don't have it - invert the baking sheet, grease the sheet with olive oil and hand form a thin pizza base from a peace of dough.
Add tomato souce, add yourre choose ingredients and cheese.
Bake your pizza at highest temperature your oven can get (ideally in a 300 degree oven) and bake for the short time (if you bake in 300 degree baking time will be about 3 minutes).
Good thoughts and physical cleanliness it's very important in production.
After cooking Vedic sastra's recommends that cleanly prepared food have to be offer to the Supreme Personality of Godhead. This is how food gets higher energy. 馃檹
So add your favorite sauce and share with friends!
