I'll have to make this some day to get a picture, but this is the way my father-in-law cooks his salmon.
2 tablespoons butter
1 1/2 tablespoons lemon juice
1 1/2 teaspoons yellow mustard
1 1/2 teaspoons Worcestshire sauce
Brush over salmon which has been placed in a greased foil pan. Let sit for about 30 minutes. Then grill until done.
