This Father's Day, what better way to treat dad than firing up the grill and throwing a backyard feast in his honor?

To really tempt his taste buds, think beyond bovine on the barbecue and liven things up with a new take on the classic hamburger.

Want to lighten things up? Why not try lean ostrich burgers or a chicken-apple bean burger? Or for the gourmet palate, how about a curried lamb and spinach burger? Or a buffalo burger with raisin-garlic mayonnaise?

Even novice grillers can expand their menus pretty easily with just a few clicks of the computer mouse.

There are a myriad of food sites on the Internet, such as SouthernLiving.com or CookingLight.com, that can help relieve barbecue boredom.

America Online's Grill to Thrill feature, available at Keyword: Grill, not only has a collection of barbecue recipes and side dishes, but you can also enlist help from the cooking experts in pairing the perfect marinade and sauces to whatever grilled goodies are on your menu.

You can also take the guesswork out of grilling with a cooking timer tool.

"If you want to go ethnic, you can easily find recipes such as Jamaican jerk turkey burgers with papaya-mango salsa and Italian sausage burgers with fennel slaw," says Carla Wojnaroski, vice president and general manager of AOL Food, the online resource with more than 18,000 recipes. "Or spice things up with Kaftah burgers, Mexican platter burgers, Moroccan turkey burgers and much more."

Vegetarians looking for more than just another ho-hum veggie burger can find outrageous recipes ranging from lentil burgers with Tzatziki sauce to black bean burgers with spicy cucumber and red pepper relish.

With the Internet putting so much great grilling information at your fingertips - like the recipe below - throw dad a barbecue feast he'll remember for years to come.
