- 4 ounces (½ cup) extra virgin olive oil
- 4 ounces (½ cup) extra virgin olive oil
- 2 ounces (¼ cup) sherry vinegar
- 2 ounces (¼ cup) sherry vinegar
- 1 large pinch fresh rosemary, chopped
- 1 large pinch fresh thyme leaves, chopped
- 1 large pinch fresh tarragon, chopped
- Salt, pepper, and crushed red pepper flakes
- 1 red pepper, quartered lengthwise, pith and seeds removed
- 1 yellow pepper, quartered lengthwise, pith and seeds removed
- 1 medium zucchini, cut on a slight bias, ¾-inch thick
- 1 medium zucchini, cut on a slight bias, ¾-inch thick
- 1 medium yellow squash, cut on a slight bias, 3/4-inch thick
- 1 medium yellow squash, cut on a slight bias, 3/4-inch thick
- 12 asparagus spears, trimmed
- 1 head endive, halved lengthwise
- 1 head radicchio, halved
- 1 lemon, halved
- Turn your grill to high, make sure it is brushed clean, and rub it with canola oil to keep the vegetables from sticking.
- Whisk the olive oil, vinegar, herbs, a large pinch of salt, a few grindings of black pepper, and a pinch of crushed red pepper flakes in a small bowl.
- Put the peppers on the grill for 2 minutes, then follow with the rest of the vegetables. To prevent the asparagus from falling through the cracks, lay them crosswise on the grill.
- Lower the heat to medium so the vegetables do not burn.
- Lightly brush each vegetable with the olive oil and herb mixture and grill 3 to 4 minutes.
- Turn the vegetables over and continue basting. (Be careful not to burn anything; the oil will cause the flames to flare up.)
- If anyone vegetable is intent on going up in flames or it is blackening or cooking much faster than the others, transfer it to the top rack or a cooler section of your grill and let the other vegetables catch up.
- All of the vegetables should take roughly 6 to 8 minutes to become tender. The endive and radicchio should be just lightly charred; remove them to the shelf or a cooler section of the grill to prevent overcooking, if needed.
- Transfer vegetables to a serving platter or individual plates and season with salt and pepper.
- Drizzle any of the remaining oil and herb mixture over the top, give it all a squeeze of lemon, and serve.
