The product is Daiya Cheddar style shreds, and I'm tellin' you what: No, it doesn't compare to the best natural organic aged Cheddar, but it's actually better than what you'll find hanging from hooks in the dairy aisle.
Here is a tuna melt. The Daiya will actually melt better than this, but I got impatient and dragged it out so I could nom it up.
My tuna salad is simple: tuna (duh), onion powder, chopped celery, salt, and mayonnaise. I add pepper at the table, because Charlie doesn't like pepper.
I could eat tuna melt until I pop, which I guess would make me a foodie fatality.
