Pre heat your oven and if you're pre mad pizza crust don't yet include a tomato passata you can place a little layer of tomato sauce on the pizza's.
Top with thinly sliced tomato and bake them in the oven for the time recommended.
While the pizza's are in the oven (or before) you can prep the olive spiders.
Do this by cutting the olives in half (lengthwise) and cut the other half to create the legs. Make as many as you'd like. I stick with one per pizza.
Once removed from the oven place a piece of basil on top, add jalapeno (optional) and whatever else you'd like to top it with while finally adding the "spiders"
