Cook ground turkey in a skillet till browned and no longer pink. Add spaghetti sauce to the skillet to heat through. Combine cottage cheese, 3/4 cup mozzarella cheese, Parmesan cheese, and egg whites in a separate bowl.
Slice 2 medium Zucchinis lengthwise as thin as possible. Set aside
Spray and 8X8 pan with cooking spray, and add 1/2 cup of the meat sauce to the bottom.
Layer sliced zucchini on top of your sauce until the bottom of the pan is covered.
Top half the cheese mixture over the zucchini.
Spread another 1/2 cup of sauce over the cheese.
Do all three layers one more time, ending with the last 1/2 cup of sauce. Sprinkle the remaining 1/4 cup of mozarella cheese on top. Sprinkle with fresh basil (optional)
Cover with foil and bake in the oven at 350 degrees F for 40 minutes. Take foil off and cook for 10 more.
Remove from oven and let sit at least 30 minutes to allow for it to set up. It can get soupy, so let it sit. Drain any water if necessary.
