I'm thinking root veggies would be good things to plant now - beets, carrots, or the like. Probably getting a bit too late and hot for lettuce and spinach, unless you have a shaded area to plant that. I'm actually going to plant some more lettuce this wknd, but I have one corner of my garden that is shaded by a large tree, so I just want to see if it'll work in that spot. I've never tried it before. If you get tomatos or peppers as already established plants, you could transplant those for a late summer harvest also.
