Mix everything together and then press into a 12″ high-lipped pizza pan and up the sides a bit.
Bake in a cool oven (GM2 300F 150C) for 20 minutes.
If still soft, continue cooking, checking ever 5 min. Drain the fat from the crust when “set”.
Top with cheeses and your choice of toppings, and return to oven to cook until toppings are done and the cheese is bubbly.
