Heat oven to 350. Using the premade crust, bake about 5 minutes, remove from oven. If making your own crust or using the canned dough, bake about the same or a little more; at least until a little brown shows.
Add in order, thousand island to your own specific amount, the corned beef, sauerkraut and swiss, either the sliced baby swiss; or shredded block swiss. Return to oven until cheese bubbles.
Remove from oven and serve while hot.
Left overs, if any, are good cold too!!
If using the pre-made pizza crusts from Wal-Mart, use the Mama Mary's. The other crunches up too much and is more like a hard cracker when baked.
