The zucchini used in this recipe are cut across to about 1-in. in length. Scoop out and discard, only 3/4 of the center.
Combine all ingredients adding the pine nuts last. Mix well.
Cook zucchini rounds in boiling salted water until al dente (slightly undercooked, still a little hard in the center), and then cool in ice water. Drain on paper, towels. Fill the zucchini with stuffing without packing too tightly and place in a casserole pan with a little oil. Let it bake for 5-10 mins. at 325ºF.
