In one sentence, describe what the following article is about:

When you’re ready to grill the burgers, press down on each to flatten it to a 4-inch (10-cm) patty. Use a basting brush to lightly cover each burger with canola oil to prevent it from sticking to the grill. Remember to brush both sides of the burgers with the oil. Place the burgers on the preheated grill. Allow them to cook on the first side for 3 minutes. While the total overall cooking time for the burgers depends on how done you want them, you should always cook them for 3 minutes on the first side regardless of whether you want them medium-rare or well-done. Once you’ve cooked the burgers for 3 minutes on the first side, use a spatula to turn them over on the grill. Let them cook for another 4 to 7 minutes depending on how done you want the burgers.  For medium-rare burgers, cook the burgers for another 4 minutes.  For medium burgers, cook the burgers for another 5 minutes. For medium-well burgers, cook the burgers for another 6 minutes. For well-done burgers, cook the burgers for another 7 minutes. Once the burgers are finished cooking, transfer them from the grill to a plate. Let the burgers sit for 3 to 5 minutes to ensure that they are juicy when it’s time to eat. When you’re ready to serve the burgers, place each one on a hamburger bun or roll. Add your favorite toppings, such as lettuce and tomato, and condiments, such as ketchup or barbecue sauce, and enjoy.  You may want to toast the buns on the grill before putting the burgers on them. Serve the burgers immediately after topping them for the best flavor and texture.

Summary:
Flatten the burgers and brush them with oil. Grill the burgers on one side. Flip the burgers and cook on the other side. Allow the burgers to stand for several minutes. Place the burgers on buns with toppings and serve. Finished.
