Astronaut cooks have made numerous attempts to wrangle hamburgers into space-ready meals, from dehydrated-pickle disks to vacuum-sealed burger bottles. Enjoy what our starry-eyed brethren never can with today’s Groupon: for $7, you get $14 worth of burgers, sandwiches, and more at Johnnie's Charcoal Broiler. This Groupon is valid at your choice of seven locations and expires June 4, 2011.

Since the first Johnnie's Charcoal Broiler began making freshly ground hamburgers in 1971, the grill gurus have mastered the art of real charcoal grilling, churning out more than 30,000 meaty spheres each week. Carnivorous canines croon for the hamburger cloaked in chili and cheese ($5.19), and patty purists gawk over the classic cheeseburger topped with Johnnie's signature sauce, mayo, and pickles ($4.79) . The veggie burger ($4.19) is a garden-graced patty with southwestern flair that often finds refuge in a mound of cheese fries ($2.99–$3.99). Johnnie's slices 500 pounds of onions each morning before hand battering the tear-inducing wheels to create one ring to rule them all, or crispy, golden mountains of onion rings to feed hungry hobbits ($2.59+). After an ideal meal, reanimate tired taste buds with the gooey blackberry cobbler ($2.59) or a slice of homemade pecan pie ($1.99).

• Had the number 8 Cheeseburger and a sweet tea. The shredded cheese makes it! Good burger! Hot fries! And good fast service! – Joe P., Yelp, 8/19/10
• Always a well-seasoned, juicy piece of meat with plenty of cheese and Johnnie sauce. Man oh man, I'm sitting in Dallas right now wishing there was one closer. – Patrick W., Yelp, 1/4/09
