Pre heat oven to 550 F degrees. Make sure the oven is pre-heated for around 30 minutes before you put the pizza to bake.
In a bowl whisk together all ingredients for the pizza base sauce - olive oil, garlic salt, tomato-chili ketchup, Italian seasoning and salt.
Roll your pizza dough to a 10 inch circle and then apply the prepared sauce on it. If you don't have tomato-chili ketchup, simply use a combination of regular ketchup and hot sauce like sriracha.
Sprinkle grated fontina cheese on top of the sauce.
Place all the toppings - grape tomatoes, spinach, pine nuts, red onion and garlic on top of the cheese.
Bake the pizza at 550 F degrees for 7-8 mins. Take pizza out of the oven and use a kitchen torch to roast the garlic (optional). You can also roast the garlic before you put it on the pizza base.
