Adults rejoiced a year ago when McDonald’s launched all-day breakfast. Now kids have their own reason to celebrate: the fast-food company is testing a breakfast Happy Meal. Starting Monday, the morning Happy Meals will be tested in 73 locations around Tulsa, Okla., USA Today reports. Kids can pick between two McGriddles, or a new Egg & Cheese McMuffin that comes without Canadian bacon, as well as apple slices or yogurt on the side. If the new Happy Meals are well-received, they could be available nationally next year.
