Preheat oven to 375°.
Heat 1 teaspoon oil in a large nonstick skillet over medium-high heat. Sprinkle chicken evenly with 1/2 teaspoon salt and 1/2 teaspoon black pepper. Add chicken to pan; cook 2 minutes on each side or until browned. Remove from pan.
Reduce heat to medium; add remaining 1 teaspoon oil. Add onion and bell pepper to pan. Cook 3 minutes, stirring frequently. Add sugar, vinegar, sage, mustard seeds, remaining 1/4 teaspoon salt, and remaining 1/4 teaspoon black pepper to pan; bring to a boil. Reduce heat; simmer 5 minutes. Add pear. Increase heat to medium; cook 10 minutes or until pear is tender, stirring frequently.
Place chicken in pan on top of chutney. Cover pan loosely with foil; bake at 375° for 15 minutes or until chicken is done.
Wine note: Pinot gris, the same grape as pinot grigio, is known for producing fuller-bodied whites brimming with fruit flavors like apple and pear when grown in the cool climate of Oregon's Willamette Valley. Ponzi Vineyards Pinot Gris 2005 ($17), with its clove and almond notes, echoes the concentrated pear and herbal flavors that are found in the chutney. -Jeffery Lindenmuth
