I like to use pepper too (I use the Montreal Steak Spice blend). I will have to try the bbq sauce, tho.

Sometimes I just add a few tablespoons of juice, such as orange or apple, etc. This gives a great flavour.

Chopped tomatoes really fine work well too.

Someone mentioned the cucumber and tomato salad ... that is my fave. I also add onion, but I am going to try to add berries as you do.
