The “BLT” (bacon, lettuce and tomato) is one of America’s most popular sandwiches. A riddle has been cited in print since at least 1994:
 
Q:  How can you use a lighthouse, a rose trellis, a windstorm and a dune to construct a tasteful image?
A: How about a beacon, lattice and tornado sand ridge?
 
A slight change—with “sand ridge” replaced with “sand witch”—was posted on the newsgroup alt.humor.puns on October 13, 2001:
 
Q: How can you use a lighthouse, rose trellis, windstorm, dune, and Halloween costume to create something tasty? 
A: Make a beacon, lattice, and tornado sand witch.
   
               
13 January 1994, Chicago (IL) Tribune, “10 more ‘winners’ the punslingers have groan to love” by Clarence Peterson, sec. 5, col. 5:
The story came to light, as such stories do each year at this time, thanks to John S. Crosbie, chairman of the International Save the Pun Foundation and publisher of the foundation’s monthly newsletter, the Pundit.
 
The foundation battles illiteracy by, for example, asking Pundit readers, “How can you use a lighthouse, a rose trellis, a windstorm and a dune to construct a tasteful image?” Readers thus rendered more literate would reply, “How about a beacon, lattice and tornado sand ridge?”
