I was feeling healthy and decided to try and make a tuna melt... but with less mayo. Not the most conventional alternative, but I subbed out the mayo for hummus and then added other delicious Mediterranean-ish things to accompany it. Using feta as the cheese and a bit of goddess dressing was also crucial.
In the end, I think I would take this over a normal tuna melt.
Hummatuna Melt - Makes enough for about 3 or 4 sandwiches
2 large cans of tuna
1/2 cup hummus
1/4 cup goddess dressing
red onions, chopped
kalamata olives, chopped
roasted garlic, chopped
bread of choice
Drain the tuna, add everything else, mix it up. Put some feta cheese on both sides of the tuna mix then grill it up and enjoy.
