"I found a Spinach Tuna Casserole recipe in a Taste of Home Cookbook. Wanted to find it here so I could print it out for reference. Found this one by the same author, but recipe is different. I wouldn't waste my time with this one. Fat free, light, low sodium, reduced fat. Eeeeecccchhhhh!!!!! What happened to your real recipe from the cookbook?"

"Great recipe! My family usually won't eat much tuna casserole but this one went over very well (other than 1 child picking out the spinach & said it would have been better with mushrooms instead), had no leftovers! I did alter it a bit - I used plain non-fat yogurt instead of sour cream, I omitted the bread crumbs, & I used a white cheese blend that I had instead of Parmesan. My hubby liked the crispy noodles on the sides ;)"

"The toping was very tasty, but laying upon plain noodles that become crispy on the bottom and side of casserole wasn't appealing."

"Tuna noodle casserole is one of my favorite dishes, especially this recipe. I love the spinach and it doesn't taste low fat at all."
