It sounds like Jackson is a lot my son. He had milk/soy intolerance and acid reflux as a baby. Once we started "real food", we had battle after battle much like the one you described above. Our Dr. started warning us around 18 months that he would eventually become a "picky" eater. He never really did. He's 30 months now, and he still eats 3 pancakes, a full serving of fruit, and drinks all his milk in one sitting. He does have days when he eats less than usual, but those are usually followed by days of eating more than usual. Some charming teacher at daycare did introduce him to cupcakes with frosting on them, bless her heart. Now we are fighting the "no you cannot have cupcakes/candy/pop/cookies for dinner" battle. So far I've been firm and haven't allowed this to happen, and he eventually quits begging and eats his green beans. We'll see. Best of luck with the upcoming year of eating!
