1Combine endive and lettuces in a large salad bowl; toss well, and set aside.
2Remove and discard the rind from the Brie; cut the cheese into small pieces. Combine cheese, olive oil, vinegar, lemon juice, mustard, garlic, green onions, and pepper in a large skillet. Cook over medium heat, stirring constantly, until the cheese melts.
3Pour warm dressing over the greens, tossing gently to coat evenly. Sprinkle salad with croutons, and serve immediately.
