Walking distance not so much, but a very short Uber ride (<2 miles) would take you to a few.
Corky's is a little to the west on Poplar (just on the other side of East I-240), that's a pretty good crowdpleaser as they cater to most types of BBQ.
Pyro's (in the SpC parking lot) is a local pizza chain that merges Subway/Chipotle style ordering with pizza which is worth checking out.
Also for barbecue a little farther east on Poplar Ave (US 72). and you get to "The one and Only" barbecue which has good and reasonable takeout, which you could then carry with you to the supercharger. Probably closer than Corky's
My favorite spot near East Memphis for out of town guests is the Germantown Comissary, which is about 3-4 miles from the Supercharger just south of Poplar/72. Funky little family owned barbecue place, not a chain.
