As far as I know, nobody around here is a doctor but from my experience, I would say that the "chick peas, a little rice and a turkey patty that had oats in it" had enough carbohydrates to raise your 2 hour reading a little high.
The 4 hour elevation, I think, is normal. Fat and sometimes the fibre (in the oats) tends to slow down the absorbtion of carbs but probably not in an even, regular manner.
Other factors that can affect your BG are medications and exercise.
You might want to try a few low carb meals (no grains, pasta, milk, ... read the old messages around here) and then do your tests.

diet does wonders when it comes to levelling out your readings
By all means, report everything to your doctor.
