Method:
Preheat oven to 375°F.
In a large skillet, heat oil over medium high heat. Add spinach and cook for 2 minutes. Add garlic, and bell peppers and cook until just tender, about 3 minutes. Stir in tomato sauce, basil, oregano, red pepper flakes, and salt and pepper. Simmer for 5 minutes then remove from heat and set sauce aside.
Coat a 9x13-inch baking dish with olive oil cooking spray and set aside.
In medium bowl mix cottage cheese, 3/4 cup of the mozzarella, and Parmesan together. Season with pepper, if desired.
Ladle about 1 cup of the reserved sauce into bottom of prepared baking dish. Top with one layer of lasagna noodles. (The fresh noodles may have to be cut in order to fit properly into the pan). Spread one-third of the cottage cheese mixture over noodles. Evenly spread another cup of sauce over that. Repeat the process until all the noodles are used, ending with the last of the sauce. Sprinkle the remaining 1/4 cup mozzarella over the top. Cover tightly with foil and bake for 30 minutes. Uncover and continue to bake until cheese is browned and the lasagna is bubbly.
Set lasagna aside to let rest for 10 minutes, then slice and serve.
