We had them for dinner tonight. We bought the beef and cheese variety, since I'm not a beef and onion fan, and those were our only two options.
The burgers themselves had pretty good taste. I couldn't taste the cheese very well, so I might add a slice next time. DH said he could taste it though.
He cooked them on the grill, and he said he is glad he did. He said coming out of the package, they were a pretty sick (not a good sick) color. He is afraid they would look disgusting if we had just microwaved them instead of throwing them on the grill for some color.
Best burgers ever? Not really. Could be thicker, could be a bit more flavorful. Convenient? Definitely.
