1 cup butter-flavored cracker crumbs (about 25 crackers)
Drain artichokes, reserving 1/2 cup marinade. Set aside. Cut artichokes into slices; set aside. In a small skillet, saute green onions in oil until tender. Add garlic; cook 1 minute longer. Remove from the heat.
In a large bowl, combine the eggs, artichokes, mushrooms, cheese, cracker crumbs, onion mixture and reserved marinade.
Transfer to a greased 13x9-in. baking dish. Bake, uncovered, at 350° for 35-40 minutes or until a knife inserted in the center comes out clean. Let stand for 5 minutes before cutting.
