First, I'd spray it with roundup to kill it, so you don't have as much
problem of it coming back.

I use Roundup sometimes, but in this case there's another possibility. You
can put down a sheet of black plastic, and after 10 days or so when the
grass has died simply cut slits where you want to plant the veggies. Then
remove the plastic when the seeds start to sprout while they're still tiny
enough not to catch on the plastic. The sod rots away and acts as mulch for
the new plants.
