I need help figuring this out.....?

so im feeding my mini dachshund 3/4 of a cup of dry dog food a day (acana) or (taste of the wild) and 1/4 of a cup of green beens. i split that meal in half one in the morning and one at night. i wanna know instead of always doing green beens if theres any veggies i could put in his food and then switch on and off.....he doesnt like carrots though,other than that hes not picky AT ALL.thanks in advance Lia!!=)
