Classic Mediterranean flavors are captured atop these piquant toasts. This recipe is adapted from Jennifer Trainer Thompson's "Jump Up and Kiss Me"(Ten Speed; 1996).
Make the relish: Heat oil in a medium skillet over medium heat. Cook onion until translucent, about 6 minutes. Stir in garlic, and cook for 1 minute. Transfer to a bowl, and stir in sun-dried tomatoes, walnuts, basil, and vinegar. Season with salt and pepper.
Make the toasts: Heat grill or broiler to medium-high. Brush bread with oil, and sprinkle with cayenne. Grill until golden brown and crisp, 1 to 2 minutes per side. Serve toasts with relish and goat cheese.
Relish can be refrigerated for up to 4 days.
