Food giant Conagra says kitchen-weary consumers are coming back to its products, helping advance a gradual recovery in some of the company’s key businesses. The maker of Slim Jim meat snacks and Marie Callender's frozen meals said Thursday that sales volumes in businesses like frozen foods and snacks are improving following pressure during a period of heavy food-price inflation. Conagra Chief Executive Sean Connolly said consumers cut back on frozen meals during peak inflation, opting to cook more meals from scratch.
