Toss asparagus with olive oil, salt, and pepper. Roast, uncovered, for 12 to 15 minutes or until crisp-tender. In a large skillet cook tomato and red sweet pepper in 1 tablespoon olive oil about 10 minutes or until very tender. Season to taste with salt, pepper, and prepared horseradish. Cool. If desired, puree for a smoother jam. Makes 4 to 6 servings.
