McDonald's introducing healthier 'Mini Meals'

The days of super-sizing fast food orders may be coming to an end. McDonald's is testing new "Mini Meals" at some locations.

Mini Meals include a sandwich or burger, small fries and a small soda for $3-$4.

The combos range from 660-820 calories.

Customers can also swap out their sides for apple slices or water for no extra charge.

It's all part of the chain's efforts to offer healthier options.
