You probably won't use all of the vinaigrette for basting the Belgian endive. So if you pour about 1/3 of it into a small bowl for basting (and only add more if necessary), you can keep the rest untouched and save it to use as salad dressing.
It's best to use a grill basket so the Belgian endive halves and any leaves that fall off during grilling do not fall through the grate.
While the leaves should remain attached during grilling, as they cook, the halves become more delicate.
