For the pizza topping:
First prepare the tomato salsa. Dice the onion and tomatoes.
Heat the pan and add little bit of olive oil (around 1 table spoon).
Add diced onion and pressed garlic.
When the onion starts to turn yellow, add tomatoes and cook, stirring occasionally, until the tomatoes are soft.
Add salt, pepper and basil and set aside to cool down.
After the temperature is lower, blend the mixture until soft.
Meanwhile, preheat the oven at 200°C and prepare the dough.
Add all ingredients into a bowl and combine well until you have a solid dough ready. Prepare a baking sheet with parchment paper.
Press the dough onto the baking sheet and bake for 5 minutes.
When you have your pizza corpus ready, spread the vegetable salsa on the dough and distribute the rest of the vegetables - bell pepper (cut in small cubes), mushrooms (cut in smaller pieces), zucchini (cut into rings), corn, rucola and olives - on top.
Bake for another 15 -20 minutes.
