Toasted Sandwiches with Tuna & Hummus

Drain tuna. Combine tuna, hummus, spinach, carrots and cumin and mix well. Make 4 sandwiches with the tuna mixture and the bread. Beat together milk, egg, and egg whites. Heat 2 large non-stick pans over medium-low heat. Carefully dip both sides of each sandwich in the milk and egg mixture, not soaking too much but using up all the mixture. Add 1/2 tsp. oil to each pan and then fry the sandwiches, 2 per pan, about 4-5 minutes per side or until golden brown. If you prefer you can skip the milk and egg mixture and just toast the bread and add the filling.
