We have a mobile gas fired pizza oven and a fresh hot pizza comes out of the oven every 2 1/2 minutes. To determine the amount of pizzas needed for your catering job, figure on an average of three slices per person. There are eight slices per pie. Exmaple: A 30 person wedding; 30×3 = 90 slices, 90÷8= 11.25 so your choice, but to have either 11 or 12 pies for your service. We also do our Little Molas side salad and Moses Lake Caesar in bulk portions.
