For the Vinaigrette
Mix breadcrumbs and thyme in a pie tin. Season the four with salt and pepper, cover the goat cheese with the flour, then dip into the beaten egg and finally into breadcrumbs. The goat cheese can be breaded and refrigerated up to one day ahead of time.
Whisk the vinegar, mustard, and minced shallot in a small bowl to blend. Gradually whisk in ½ cup of canola oil, and the ¼ cup of walnut oil; season to taste with salt and pepper. Combine mixed greens, Belgian endive and pears in large bowl. Place the walnuts on a parchment lined sheet pan and toast in a 325ºF oven for about 10 minutes.
Heat the 4 tablespoons of olive oil in a skillet over medium heat. Working in batches, add cheese rounds to skillet and cook until crisp and brown on outside and soft on inside, about 2 minutes per side. In a large bowl toss the salad with salt, pepper and enough vinaigrette to coat the greens. Divide among 4 plates. Place 2 warm cheese rounds in center of each salad and sprinkle the walnuts over the top.
