Cook eggplant, zucchini, onion and capsicum, on a heated oiled grill or BBQ until vegetables are browned lightly and just tender. Mix vegetables together in a medium sized bowl (or on a serving platter).
Combine garlic, oil and vinegar in a small screw-topped jar; shake well.
Drizzle vegetables with balsamic dressing; toss gently to combine.
Serve with fresh basil leaves (if using).
Top tip:
Make the dressing while vegetables are barbecuing to save time.
