1In 4-quart Dutch oven or saucepan, melt butter over medium-high heat. Add chicken, onions, celery and garlic; cook 7 to 12 minutes, stirring occasionally, until chicken is no longer pink.
2Add frozen mixed vegetables, broth, parsley, poultry seasoning, salt and pepper; mix well. Heat to boiling, stirring frequently. In small bowl, mix milk and flour until smooth. Add to chicken mixture; cook and stir until mixture boils and thickens. Reduce heat to low.
3Separate dough into 5 biscuits. Cut each biscuit into quarters. Arrange biscuit pieces evenly on top of chicken mixture; sprinkle with paprika. Cover tightly; cook 30 to 35 minutes or until biscuits are fluffy and no longer doughy.
