Pear & Blue Cheese Pizza w/Caramellized Onions

(Original recipe from Catherine of Albion Cooks

this is an uncooked pizza, taken before I added the walnuts and put it into a Foodsaver bag

2 small onions, thinly sliced
1 c water
1 T olive oil
1 t sugar
4 8-inch Boboli pizza crusts
4 t olive oil
2 c shredded mozarella cheese
1 pear, thinly sliced and sprinkled with 2 t lemon juice
1 4-ounce package Treasure Cove blue cheese, crumbled
1/2 c coarsely chopped walnuts

First, steam the onions in the water in a skillet, covered, for about 10 minutes over medium-low heat, or until water has evaporated. Add olive oil and sugar, and continue to sauté until onions are lightly browned. Remove from heat. Brush each pizza crust with a teaspoon of olive oil. Top each with 1/2 cup mozarella, one-fourth of the pear slices, one-fourth of the blue cheese, and one-fourth of the chopped almonds. Bake at 450˚ about 10 minutes.

After the pizzas were all assembled, I vacuum-packed each one with my Foodsaver, and put them in the freezer. Once work starts, I can just take one out, put it in the refrigerator at the office to thaw, and then cook it for lunch!
