In a medium bowl, place pasta sauce, mushrooms, cottage cheese, egg, parsley and oregano. Stir until well blended.
Spray 3 qt rectangular casserole dish.
Wash new potatoes and carrots. Peel and slice 1/8th thick. Place carrots in microwave bowl and cook 2.5 minutes.
Arrange 1st layer of potatoes overlapping edges in prepared casserole dish. Sprinkle with 1/4 cup diced onions, salt and pepper. Spread 1/2 pasta and cheese sauce over potato layer. Spread layer of 1/2 the swiss cheese.
Repeat potato layer over pasta and cheese sauce. Top with 1/2 of carrots, 1/4 cup onions, and salt and pepper. Arrange balance of potatoes and carrots on top with pasta and cheese sauce. Top with onion ringlets and sprinkle with Parmesan cheese, rest of swiss cheese and olives.
Cover with foil and bake 40 minutes at 450 degrees. Remove cover and brown top for 7 minutes, or longer. Let stand 10 minutes before serving.
Number of Servings: 6
Notes from Nicci: We didn't use the mushrooms or olives because I don't like them and my hubby is VERY sweet and accommodating of my various food issues.... I don't think it was lacking in any way leaving these out. Next time I may pre-cook the potatoes a min or two in the microwave like the carrots, I thought they could've used a tad more cooking. And I think I'd get a bit more potatoes as well. It was hard to cut them 1/8 inch thick so I probably cut them more like 1/4 inch think, and I sort of ran out for the third layer. Again, this didn't make a difference, but I know for next time. And there will be a next time!
Also, it was so SO GOOD that we each ate more than we should have (given the amount of cheese in it) and I'd say more like number of servings is 4. Make extra if you have company! Great paired with homemade bread!
