NEW YORK -- If you think a Whopper's too indulgent but are sick of chicken sandwiches, Burger King is offering a turkey burger for the first time.

The Miami-based company is rolling out the new sandwich this week as part of its limited-time offers for spring, marking the latest fast-food effort to cater to health-conscious diners. Last week, McDonald's said it plans to offer a lower-calorie version of its Egg McMuffin made with egg whites. The Oak Brook, Ill.-based chain said the egg whites will be available for any other breakfast sandwich on its menu as well.

Burger King said its turkey burger could be added to the permanent lineup if sales are strong enough.

Showing that the healthy glow isn't strictly about calories, Burger King's turkey burger clocks in at 530 calories, compared with 470 calories for its grilled chicken sandwich. A regular Whopper is 630 calories.

Although beef prices have been climbing and pressuring restaurant chains, Haley noted that chicken and turkey remain more expensive because the supply chains are still far smaller than for beef. That means turkey burgers at Carl's and Hardee's are more expensive than beef burgers of comparable size.

At Burger King, the suggested price for the new turkey burger is $3.99, compared with $4.29 for its new Chipotle Whopper, which is also being introduced as part of the spring menu.

For those who want something more indulgent, Burger King is also offering a Bacon Cheddar Stuffed Burger, which includes a ground beef patty stuffed with smoked bacon and cheese.

It's also offering loaded tater tots stuffed with bacon and sweet onions, a pina colada smoothie, "Donut Holes" and a trio of iced teas.
