Microwave Tuna Casserole

My family digs into this moist, flavorful tuna casserole. Crisp celery along with zucchini and tomato give it a fresh twist. When I get home from work and we have to be somewhere else in 90 minutes, this is the recipe I rely on.

    This turned out quite well and very tasty. I was unsure how we would like the dill flavour but it was good, not too powerful. I omitted the salt, used plain yogurt instead of sour cream and I did use light mayonnaise and it worked fine for me. Will make again for sure!!!

    wonderful recipe. I have used greek yogurt in place of mayo and fresh dill and basil for spices. Kids love it and it is one of our fav recipes

    I have been making this recipe since I first found it a few years ago. It's easy to make and very tasty! Love the addition of the zuchini in the dish. I it most of the time as written. I have sometimes added more cheese, but that's a personal preferance of my family. THANKS for sharing the recipe...it is excellent!
