Easy... You create a diet base based on the stapple veggies and fruits and every once in a while, you can add other veggies into the mix. This way he/she can have varieties. While the veggies that are listed to be fed occasionally or rarely may not be good for everyday feeding, they do contain other important vital nutrients, and by adding it to the diet base, you are giving your bearded some important nutrients to keep him healthy. I usually add the other veggies into the staple mix at least every other week for several days for this reason. Note: I add the occasional veggies that are listed as to be fed on occasion to the staple mix instead of giving to them on their own. This way they don't get a full dose of them and he's only eating a little at a time, spreading it out for several days, avoiding one, big, full dose; it's better that way. Kindda like we humans eating varieties of food...a little of that and a little of this. That's why we should also eat varieties...
