Place the warm water in the large bowl of a heavy duty stand mixer. Sprinkle the yeast over the warm water and let it sit for 10 minutes until the yeast is dissolved.
Add the flour, salt, sugar, and olive oil, and using the mixer. If you don't have a mixer, you can mix the ingredients together and knead them by hand. The dough should be a little sticky, or tacky to the touch. If it's too wet, sprinkle in a little more flour.
Transfer the dough into a lightly greased bowl. Turn to coat and cover for about 2-3 hours, or until it double the size. For a quick rise, place the dough in a warm place (75°F to 85°F) for 1 ½ hours.
While waiting for the dough to rise, prep sauce and toppings. Combine canned pizza sauce and banana ketchup. Thinly sliced onion and bell pepper. Set aside.
After the dough has risen, grease a 10x15 inch dark non-stick pan with a little bit of olive oil. Preheat your oven to 450 F. Take the dough, and using its own weight, allow it to form a rough rectangle as you lift it. Lower it on the baking pan and pat and press it to occupy the space of the pan.
Add olive oil and rub it over the dough. Add in pizza sauce, mozzarella cheese, bell peppers, onion and longganisa.
Bake in a pre-heated 400 F oven for 10-15 minutes or until the edges of the crust is golden and the cheese has melted. Serve and sprinkle with chili flakes and cilantro.
