Portobello Mushroom Tuna Melt

READY IN: 25mins
Recipe by McGelby

This is a tasty recipe from Lifetime's Cook Yourself Thin, DH and I tried this for dinner last night and really enjoyed it. Only changes I plan for the next time is to leave the greens on the side as it made things messy and maybe to use about half the parsley. 1 serving is 2 melts. I hope you enjoy!

Very tasty sandwich, it is going into recipe rotation. Cut the parsley as recommended. I put the tuna mixture on the mushroom and returned it to the broiler a few mins. before adding the cheese and tomato to get it heated without charring the cheese.
