Cut goat cheese into discs about 1 inch thick. Lay discs on a plate and sprinkle with chopped thyme and chopped rosemary.
Drizzle with extra-virgin olive oil and turn cheese over to coat both sides
with oil and herbs.
Preheat oven to 400°F.
Dust both sides of each disc with breadcrumbs. Set directly on a baking sheet and bake until cheese is warm and puffy and crumbs have begun to brown, about 5 minutes.
To serve, dress a mixture of little gem and frisée lightly with a good vinaigrette. Put a handful of dressed lettuces on each plate and set warm goat cheese discs beside them. Garnish with thinly sliced watermelon radishes.
