SPACE FOOD STICKS
Space Food Sticks were produced originally in 1971 by Pillsbury. You can still buy them today from spacefoodsticks.com!
Their website also has some classic period Space Food Sticks TV commercials.
I remember my neighborhood friend had boxes and boxes of these things, and one day we went through every single box. I'll bet his mom was ticked!
