Sassy Salmon Burgers

In medium bowl, combine salmon, 1/2 C. wheat germ and green onions. In small bowl, beat together 2 egg whites, 2 Tbs. water, mayonnaise, salt and hot pepper sauce; add to salmon mixture, mixing well. Shape into 5 patties, each about 1-inch thick. In shallow dish, place remaining half-C. wheat germ. In second shallow dish, beat remaining egg white with remaining 2 Tbs. water until frothy. Dip salmon patties, one at a time, into wheat germ, then into egg white mixture, then again into wheat germ. In large nonstick skillet, heat oil. Cook patties over medium heat 3 to 4 minutes on each side or until golden brown and heated through. Serve patties on buns with avocado, tomato slices and spinach.
