First mix the egg with the can of tuna and stir with a little salt and pepper to a mixture. Spread evenly on a baking sheet lined with baking paper and bake at 200 ° C for approx. 10 - 15 minutes.
Then mix the tomato paste with a dash of water, salt, pepper and a few herbs of your choice and spread on the finished pizza base.
Top it as you like (in my example with salami, chicken, tomato, jalapenos & cheese) and then put it in the oven again for about 15 minutes at 200 ° C.
