Portobello Mushroom Tuna Melt

Total Time
Prep 10 mins
Cook 15 mins

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.

The DM and I have just enjoyed these for lunch though I was struggling to get through 2 so next time I'll make it 1 with a small side salad. The only difference I did was to put the cheese on top of the tomato and then put under the grill/broiler and I did initially cook my mushrooms in the oven (175C for 12 minutes - didn't turn though) and I used shredded baby cos leaves for the baby greens. Thank you McGelby, made for Iron Chef - and THE SECRET INGREDIENT is.....
