Cafe Rossini in Mineola makes a great sausage, potato and onion pizza on Fridays only. I try to have a slice any Friday that I happen to be in the area. It's a grandma sicilian style crust and has crumbled sauage (the real kind not kibble), potato cubes and onions. They usually run out by 3:00 pm so get there early. If they run out by the time you get there, don't worry have a slice or two of the old fashioned sicilian (sauce and grated cheese no mozz). They will make a whole sausage potato onion pie to go on request.
