Removing grass from a vegetable bed

One of my vegetable beds used to be primarily lawn. And it has made a few valiant attempts to return to lawn. When I first removed the grass, I simply turned some of it over and stacked other parts of the turf upside down. This time, I have attempted to put as much of it in the compost heap as I could. I'm keen for as little grass to grow here in the future as possible because of the difficulty of getting the soil out of its roots. This means it takes much longer to clear than a lot of weeds. I didn’t have the time or energy to finish it all this weekend, but I made a good start.
