Step 1Cut tofu into 1/2-inch slices and drain on paper towels, patting dry, then cut into 1/4-inch cubes.
Step 2Heat butter and oil in small skillet over medium heat until butter is melted and skillet hot. Saute tofu until lightly browned, stirring, 2 to 3 minutes. Add 2 tablespoons green onion and salmon and saute over medium-low heat 1 minute. Stir in eggs. Cook until outer edges of eggs are set, then slowly stir as for scrambled eggs. Divide eggs between 2 bagel halves. Spoon dollops of sour cream atop eggs and garnish with green onion. Serve with tomato wedges.
