Hazırlanışı
1Cook eggs in a large saucepan of boiling water 7 minutes. Drain and place in a large bowl of ice water; let cool.
2Prepare a grill for medium-high heat. Rub halibut with 2 Tbsp. oil; season with salt and pepper. Grill, skin side down, until skin is charred and fish is nearly cooked through, 5–8 minutes. Turn and grill just until cooked through, about 1 minute. Transfer halibut to a plate and remove skin.
3Toss vegetables with remaining 1/4 cup oil in a large bowl; season with salt and pepper. Grill, turning occasionally, until lightly charred and tender. Time will be different for each vegetable (about 2 minutes for scallions and garlic scapes, 4 minutes for Romano beans, 8–10 minutes for eggplants, 10–15 for potatoes). Transfer to a plate as they are done.
