One of my favorite vegetables!
Approximate quantities: 1 1/2 lbs of romano beans, trimmed; 1 tablespoons olive oil; 1 tablespoons grapeseed oil; 4-6 garlic cloves; salt and pepper
Wash and trim the romano beans, place in a large, rectangular Pyrex baking dish or on a sheet pan, drizzle with oils, crushed garlic cloves, salt and pepper an hour or so before grilling
Grill in a grill basket on medium-high heat for about 10-12 minutes, turning them, or vigorously shaking the grill basket halfway through
The variable here is your grill and it’s temperatures. I’ve provided a heat and time range for everything that should work for almost all grills.
Almost everything needs to be turned, or if it’s in a grill basket a good shake at the halfway point will work, so what I’d recommend is plan to check it and turn it halfway through the shorter time range that I suggest, and then, to check it again for doneness, at the end of the shorter time range. This way, if you grill doesn’t run as hot, and you can see that you need more time, it’s easy to leave the second side on for a few more minutes.
