1. On a small rimmed plate, mix bread crumbs and 1 1/2 teaspoons herbes de Provence. Coat chèvre log with 2 tablespoons olive oil, then gently roll the log in bread-crumb mixture. Place on a baking sheet and bake in a 400° regular or convection oven until bread crumbs are golden, 10-12 minutes. Let cool slightly.
2. Meanwhile, spread pine nuts in a small baking pan; toast in same oven until light golden, 3 to 5 minutes. Let cool.
3. Combine corn kernels with 1 cup water in a 1- to 1 1/2-quart pan over high heat; bring to a simmer and cook just until corn kernels are heated through, about 2 minutes. Drain, rinse with cold water, and drain again.
4. In a large bowl, whisk remaining 5 tablespoons olive oil, vinegar, garlic, mustard, and remaining 1/2 teaspoon herbes de Provence until smoothly blended. Add salt and pepper to taste.
5. Add salad greens, corn kernels, nectarine, raspberries, blueberries, and half the pine nuts and mix gently to coat. Divide among salad plates. Cut chèvre into 1/2-inch slices or chunks. Top salads evenly with chèvre, remaining pine nuts, and lavender blossoms.
