HI - I want to make a lasagna but my husband has a cow cheese allergy. He can eat sheep and goat's milk cheeses. I can probably sub goat cheese for the ricotta, but is there anything I can use for the mozz? Has anyone tried it? I use manchego for him on burgers to make cheeseburgers, but somehow I don't thing that taste will go with the lasagna. ALSO, he loves grilled cheese, cheeseburgers - is there another good melting sheep/goat cheese besides the manchego? Thanks!!
