  We analyze primordial non-Gaussianity in single field inflationary models
when the tensor/scalar ratio is large. Our results show that detectable levels
of non-Gaussianity $f_{NL} \sim 50$ are still possible in the simplest class of
models described by the effective theory of inflation. However, the shape is
very tightly constrained, making a sharp prediction that could be confirmed or
falsified by a future detection of non-Gaussianity.
