I have not tried these yet, putting here for safe-keeping. Looks like they would be a terrific addition to the holiday buffet table or to serve as an hors d'oeuvre before dinner or at a cocktail party.

Polenta Squares, recipe follows
4 cups water
1 cup polenta
2 teaspoons salt
1/2 cup grated Fontina or Monterey Jack
1 tablespoon minced jalapeno

Steps:

  • Preheat a gas or charcoal grill. Thread the sausages, red and green bell pepper pieces, and onions alternately onto the skewers.
