I got this recipe from my aunt who found it I believe on She had started Atkins and has lost 93 pounds so far...well, I just started Atkins and found this recipe to be one of my favorite quick meals.... and I didn't like tuna that much before!

Ingredients Nutrition


  1. Mix the can of tuna with mayonnaise, salt and pepper and any other herbs or seasonings you`d like to add, walnuts taste good in it too- Be creative and have fun with it.
  2. Put tuna mixture aside.
  3. Cut a slice of your tomato and set aside.
  4. Over medium- low heat, sauté the sliced mushrooms in olive oil until slightly crisp- I sometimes add left over chicken or a slice or 2 of bacon to the sauté for variety.
  5. Once the mushrooms are sautéed arrange them into a tidy little circle and place the tuna and mayo mixture very carefully onto the center of the mushroom platform- If you haven`t realized by now-- the mushrooms replace your bread.
  6. Then place the tomato slice on top of the tuna and mayo, top it all off with cheese, reduce heat slightly, and cover for 1 minute or until the cheese is melted.
  7. Carefully, with the aid of a flexible spatula, slide the tuna melt onto your plate- or a leaf of lettuce on your plate and enjoy.
  8. Only 3 and a half carbs for the whole meal-- and it`s filling.
  9. You can use other types of cheese and mushrooms or even more tomato, but take the carbs into account- some cheeses are higher than others and the same for veggies too.

Terrific!!! I've made it twice so far. I added dry mustard to the tuna mixture and to the mushroom saute. I sliced the mushrooms in the food processor ahead of time.Pecans are incredible in the mushroom saute. I can see how this can be very versatile. My husband Dan, really like this. Thanks!!! LisaJo
