GMSH usually works nicely. I usually write the nodal coordinats of the
outlines to a file, read them with Python, call gmsh in batch mode, and
then start a new simulation from scratch (no state variables to be
mapped). Not effiecient nor elegant, but at least this works more
reliably than calling Triangle from within Libmesh.

If I remember correctly, gmsh is using Triangle internally (did not check).

Would be nice to have a better generic solution, though.

Best, Martin
