This recipe was the result of a missed shopping trip. Kinda threw everything together one night and created a hit. It has become a staple at our family get-togethers. Even the children, especially my 3 year old son, absolutely love it. Using garlic Alfredo sauce adds a little extra flavor.
Bring a large pot of salted water to a boil. Cook pasta in boiling water until al dente', drain.
Preheat oven to 425 degrees.
In a large bowl, thoroughly mix: noodles, onion, 1 cup cheese, peas, tuna, Alfredo sauce, and spinach. Transfer to a 13 X 9 inch baking dish, and top with bread crumbs and remaining 1/2 cup cheese. Bake 15-20 min. in a preheated oven or until cheese is bubbly.
