Instructions

1. 1

   Bring a large pot of lightly salted water to a boil. Cook lasagna in the boiling water, stirring occasionally until cooked through but firm to the bite, about 8 minutes. Drain.

2. 2

   Preheat oven to 375 degrees F (190 degrees C).

3. 3

   Melt margarine in a skillet over low heat; cook and stir flour, salt, and pepper into the melted margarine until smooth and bubbling, 2 to 3 minutes. Add milk and broth into flour mixture, stirring constantly; bring sauce to a boil. Stir wine into sauce and remove from heat. Stir Parmesan cheese into sauce until smooth.

4. 4

   Whisk ricotta cheese, egg, and egg white together in a bowl.

5. 5

   Heat olive oil in a skillet over medium-high heat; saute carrots, zucchini, and spinach until just becoming tender, 5 to 10 minutes. Stir vegetable mixture into ricotta mixture.

6. 6

   Layer 1/3 the lasagna noodles, 1/3 the ricotta-vegetable mixture, and 1/3 the Parmesan sauce in a 9x13-inch baking dish; repeat layering 2 more times with remaining ingredients, ending with a layer of mozzarella cheese.

7. 7

   Bake in the preheated oven until cheese is lightly browned and bubbling, about 30 minutes.
