Sauté onion in hot oil in a large Dutch oven over medium heat 7 minutes or until tender. Add garlic, and sauté 1 minute. Stir in turkey and next 8 ingredients. Bring to a boil, stirring occasionally; reduce heat, and simmer 15 minutes. Serve with desired toppings and Green Chile Biscuits.
To make Green Chili Biscuits:
Stir together baking mix and remaining ingredients until a soft dough forms. Turn dough onto a lightly floured surface; knead 3 or 4 times.
Pat or roll dough to a 1/2-inch thickness; cut with a 2 1/2-inch round cutter, and place on an ungreased baking sheet.
Bake at 450° 10 to 12 minutes or until biscuits are golden brown.
