There’s not too much to grilling oysters, and thank God for that. I like to leave the high maintenance stuff to other people (!!!)
Preheat the grill to medium/medium high. Basically, get the grill hot. Throw your oysters on and shut the lid, grill the oysters until they pop open. As the first ones open up, I put them on the top basket/bread area of the grill so they stay warm but don’t stay on the direct heat.
Saute the onions in the butter. Add the wine and simmer for 7-10 minutes, letting some of the liquid reduce down. Add the jalapenos and garlic, simmer a little longer…
Pour sauce on top of the opened oysters. Enjoy!
