Looking around in the fridge for something to marinate a few cb's in, I spotted a bottle of Mararita mix, w/Tequila.
Poured about 2 cups into a zip-lock, added a little s&p, splash of oil, and original Mrs Dash. Put each breast in a another bag and pounded with fist until even thickness, not very thin.
Marinated for about 3 hrs, and grilled on the 220. (didn't time, but not long)
Gave a light sprinkle of Weber seasoned salt when about done.

These were the most juicy/tender cb's I've ever made. No over-powering flavors, the meat spoke for itself.
I mainly credit the Weber Q, and of course this website for inspiration, and tips.

Wow that looks good. I need to get off my duff and get my Q fired up soon. Give some credit to the cook too now ~_^

very nice, very nice. red rules !
