    The recipe sounded really good but they turned out bland. I added a little brown sugar hoping the sweet would cook in with the butter and it was still bland. Would not make this again.

    I have been making these "little-goodies" for years on the grill. If you like onion soup, you will love this. Fresh pepper is good on them, no need for salt because of the bouillon cube.
