Grilled Tuna with Provençal Vegetables and Easy Aioli

This vibrant grilled tuna with Provençal vegetables is a wonderful way to enjoy fresh, Mediterranean flavours. The combination of meaty albacore tuna steaks and charred summer vegetables makes for a satisfying, low-carbohydrate meal that is naturally colourful and packed with nutrients. By grilling the aubergine and courgette, you achieve a smoky depth that perfectly complements the fragrant herbes de Provence and the punchy garlic finish.

How to make Grilled Tuna with Provençal Vegetables and Easy Aioli

Spray grill with nonstick spray. Prepare barbecue (medium-high heat).

Brush tuna steaks, courgette, and aubergine with olive oil; sprinkle with salt and pepper. Grill vegetables until tender and lightly charred, turning occasionally, about 12 minutes. Remove from grill and cut into bite-size chunks. Place vegetables, tomatoes, herbes de Provence, and garlic in large bowl; toss to blend. Set aside. Grill tuna steaks to desired doneness, about 4 minutes per side for medium-rare. Place tuna on plates, top with vegetables, and serve with aioli. * A dried herb mixture; sold in the spice section of supermarkets and at specialty foods stores. If unavailable, a combination of dried thyme, basil, savory, and fennel seeds can be substituted.
