Tofu is nutritious, but how do you work it into your diet? The miracle of tofu (soybean curd) is that it has almost no flavor of its own, so it takes on the flavors of nearby ingredients. The miracle of this recipe is that, because soft tofu is similar in consistency to ricotta cheese, the soybean curd blends anonymously into the lasagne, providing a nutrition boost your diners won't suspect.
Boil lasagne noodles in salted water until al dente; drain and cool.
Saute chopped onion and minced garlic in olive in a skillet over medium heat until the onion is soft. Add thawed, drained spinach and mix well; remove from heat.
Combine the ricotta cheese, tofu, Romano or Parmesan cheese, herbs and egg in a mixing bowl and mix well.
Build the lasagne. Line your baking pan with lasagne noodles; cover with a thin layer of spinach mixture; spoon on a thin layer of the cheese/tofu mixture; sprinkle with grated mozzarella; ladle on a bit of pasta sauce.
Cover with another layer of noodles, and repeat steps above. End with noodles as the top layer; pour the remaining pasta sauce over the top; sprinkle remaining mozzarella over the top.
Cover with aluminum foil and bake in the center of a 350 degree F oven for about one hour; remove and let cool at least 15 minutes before serving.
