Maybe some rare or unusual one or two but none of the commonly grown vegetables.

I suppose one could claim green beans IF they cross and IF are let go until the pod is swollen full of some cross-pollinated seeds that the taste 'might' be affected to a small degree but that's a lot of IF's and unusual. Or pumpkins by those who roast and eat the pumpkin seeds.

But I can't think of anything else off hand besides corn where eating the seeds is the primary goal and even with corn most don't even notice the effects except for color.
