This was so good! What a great way to enjoy tuna & zucchini! I used half fat free mayo/half fat free plain yogurt, red onion instead of green, dried parsley & low fat mozzarella (I only used about 1 tbsp-enough for me!). I didn't use any tomato, peppers or onions & tossed the zucchini slices (I used about 8 small slices) with some salt & oregano. What an enjoyable meal! Thank u for sharing this.

Ingredients Nutrition


  1. Slice the zucchini into diagonal 'coins'.
  2. Saute zucchini in a single layer in a saute pan with a little bit of oil until they begin to brown, then turn over and brown the other side a little (this is to both heat them and eliminate a little of the moisture in them).
  3. Mix drained tuna with parsley, olives, green onions, mayonnaise and mustard (you can swap out ingredients here--try pickled red peppers, capers, celery, brown onion, swap out different peppers for greater or lesser heat--whatever you have on hand).
  4. Arrange zucchini in small piles on a foil lined baking sheet: I used 4-5 pieces per pile and just slightly overlapped their edges.
  5. Mound tuna onto zucchini bases.
  6. Cover each tuna-zucchini mound with a few slices of tomato and then sprinkle with cheese.
  7. Place under a broiler until cheese is melted and beginning to brown.
