Starting a patch from scratch

Where I mulched the veg patch last year with grass cuttings resulted in masses of grass seedlings the next spring.

Best to cut the grass before the seeds form. Though I don't find grass seedlings too hard to pull out as their roots are shallow, just a bit of an annoyance. Our Linkabord raised beds absolutely cook in the sun so a few weeds doesn't bother me as much as having to water so frequently and rewet bone dry soil.
