This is from a box of lasagna noodles (don't know the brand) from years ago and its the recipe that I like a lot - hope this helps if nobody comes up with the exact recipe that you're looking for.

VEGETABLE LASAGNE

1 pound lasagne noodles, cooked and drained
1 cup (4 oz.) shredded fontina cheese
1 package (10 oz.) chopped spinach, thawed and drained

1 cup shredded zucchini
3 cups part skim milk ricotta (divided)
1 egg
1 onion, chopped
2 tablespoons oil
2 tablespoons flour
1/4 teaspoon nutmeg
1 cup chicken broth
1/2 cup grated Parmesan cheese

Mix together fontina, veggies, 2-1/2 cups of the ricotta and the egg.
Place layer of noodles in 13 x 9 pan. Spread half of ricotta mixture. Repeat layers, ending with noodles on top.
Cook and stir onion in oil under tender. Stir in flour and nutmeg. Stir in chicken broth and 1/2 cup ricotta. Cook and stir until mixture comes to a boil. Spoon over lasagna. Sprinkle with Parmesan. Cover and bake at 350 for 45 minutes. Uncover and broil about 2-3 minutes or until lightly browned.
