I'm not sure how large you think the servings are likely to get, but a quick look indicates 1 cup of cooked and drained peas has 35% DV of dietary fiber. Before you eat yourself into some kind of iron-related jeopardy your digestive tract is going to raise some warnings of its own, I think.
Serving Size: 1/4 cup (27g) has 35% of RDA of Iron.
I'm not the OP, just gave it a quick search. That's for pea protein. Further down-thread absorption is brought into play, which is likely why the risk is less than it would appear.
