QUICK Grilled Onion Appetizer Pizzas

   Grilling caramelizes the natural sugars in onions;  the flavor is unbeatable.

      2  large purple onions
      3  Tbsp olive oil, divided
1 1/2  Tbsp minced fresh rosemary
   1/2  tsp ground cinnamon
   1/4  tsp salt
   1/4  tsp ground red pepper
      4  (6 inch) Italian bread shells
      1  (4 oz) pkg crumbled blue cheese
   1/2  cup chopped walnuts, toasted

    Cut each onion into 4 (1/2 inch thick) slices.

    Combine 2 Tbsp oil, rosemary, and next 3 ingredients;  brush over both sides of onion slices.

    Cook onion, covered with grill lid, 4 to 5 minutes on each side or until browned and tender.  

    Brush tops of bread shells with remaining 1 Tbsp oil;  cook, without grill lid, 1 to 2 minutes.

    Sprinkle with crumbled cheese; top with onion, and sprinkle with chopped walnuts.

    Cook, covered with grill lid, 5 to 7 minutes or until cheese melts and bread shells are golden.

    Cut into wedges, and serve immediately.
