For the salad: Place the tomatoes on a baking sheet, drizzle with some olive oil and sprinkle with salt and pepper. Roast until tender and starting to brown, about 20 minutes. Let cool.
Meanwhile, toast the pecans in a large skillet over medium heat, tossing occasionally, until fragrant, 3 to 4 minutes. Let cool, then chop.
For the vinaigrette: Whisk together the champagne vinegar, orange juice, honey, Dijon and shallot in a medium bowl. Slowly whisk in the olive oil; season with some salt and pepper.
For the goat cheese croutons: Heat the vegetable oil in a medium skillet over medium-high heat. Slice the goat cheese into 8 equal rounds. Add to 3 shallow dishes, the flour, egg and panko. Coat each goat cheese round with flour, then egg and then panko, shaking off excess, and fry until golden on both sides, about 1 minute per side. Transfer to a paper-towel lined rack or plate.
To assemble the salad, toss the greens, pear, pecans and tomatoes in a large bowl. Drizzle with some vinaigrette and gently toss to fully combine. Divide the salad among 4 salad plates, top each with 2 goat cheese croutons, and serve.
