Cook lasagna noodles according to directions.
Preheat oven to 350 F.
Combine bell pepper and spinach in a medium size bowl.
In a large bowl, combine pasta sauce, diced tomatoes, ricotta cheese, 1/2 of the shredded cheese, and basil. Stir to combine.
Scoop 1-2 cups of sauce into a 9 x 13" pan (enough to cover the bottom.)
Add 1 layer of noodles.
Add 1/2 of the vegetable mixture.
Repeat until ingredients are gone.
Top with remaining shredded cheese.
Cover with aluminum foil. Bake for 60 minutes or until cheese is melted in the middle on top.
