Subway isn't taking this laying down.
The sandwich chain is fighting back against a claim that the chicken it serves up isn't all real chicken, WCBV 5 ABC reports.
Canadian researchers say a DNA test shows the oven-roasted chicken is just over half chicken with the rest made up of soy.
Subway said it can't confirm any of the testing methods used but did say it uses about 1 percent of soy protein for texture and moisture.
The same test found other fast food chains had about 85 per to 90 percent chicken as opposed to Subway's 50 percent.
Researchers also ran DNA tests for chicken products at McDonald's, Wendy's A&W, and Tim Horton's — all of which contained at least 84.9 percent chicken DNA and no more than 90 percent.
