Hmmm maybe a little corn might just work and I'm unlike my earlier years willing to go "out of the box" some in carefully measured steps in trying something different . Typical traditional succotash would probably be too complex with all the extra beans and stuff to work in our recipe.
DH and DS HATE lima beans too. When DS was itty bitty and I would cook chicken pot pie, he would eat his whole serving and afterwards spit out each individual lima bean-one at a time! That always amazed me. He would do the same thing when I would feed him yogurt with fruit...eat the serving of yogurt and spit out each bite of fruit at the end.
When I was a kid, my family used to sit around and drink beer. I thought, that's not for me. Then when I grew up, I tried one, and voila..... I drink it all the time now. Go figure.
