Preheat oven to 375 degrees F. Lightly coat a 3-quart rectangular baking dish with cooking spray; set aside. In a Dutch oven cook lasagna noodles in a large amount of boiling water for 10 to 12 minutes or until tender but still firm. Drain noodles; rinse with cold water. Drain well.
Meanwhile, place a steamer basket in a Dutch oven. Add water to just below the bottom of the steamer basket. Bring water to boiling. Add broccoli, sweet pepper, zucchini, and yellow summer squash. Reduce heat. Cover and steam for 6 to 8 minutes or until vegetables are crisp-tender. Remove from heat.
Layer three of the cooked noodles in the prepared baking dish. Spread with one-third of the ricotta cheese mixture. Top with one-third of the vegetable mixture and 2/3 cup of the mozzarella cheese. Repeat layers twice.
Bake, covered, for 50 to 55 minutes or until heated through. Uncover; let stand on a wire rack for 10 minutes before serving.
Meanwhile, for salad, in a medium bowl combine mixed greens, apples, grapes, and Essential Everyday Vinaigrette; toss to coat. Serve salad with lasagna.
