That's the key, but have the vacpac ready when it's hot off the grill and start stuffing bags and seal hot.... Savors the flavors and moisture... Plus it will pull in more flavor as it thaws so add some sort of flavor prior to sealing, personally I like a sweet/spicy bbq sauce in light amounts with some tapatio sauce for some extra kick oh and don't forget about a couple good shakes of cracked black pepper...
