In a medium skillet over medium-high heat, brown the ground beef with diced onion and seasonings. Transfer to a serving bowl, if desired.
Use scissors to cut each bag of chips in half. Make sure the chips are distributed evenly between the two halves.
To serve, set out the half bags of chips alongside the meat, lettuce, and whatever optional toppings you've chosen. Allow people to build their own walking tacos by adding meat and the other toppings to their individual bags of chips.
