I don't see why not as long as it's not too many. Peas are good for the kidneys and have Iron. I use them in my dog food.
Carrots are good. Pumpkin is good. Green Beans.
NO GRAPES, RAISINS, or SULTANAS.
Sometimes ours get mango, pineapple.
My rule is if you're feeding kibble. Other foods shouldn't comprise more that 15% of the total daily consumption. Otherwise you may throw the Cal/Phos ratio out of whack.

Or give your dog diarrhea.
