Is the "center of the meal" the part that provides the most volume and mass, or is it the part with the most calories? My lunch today was a full pound of bok choy (raw weight), 2 Tbsp avocado oil, 4 oz of steak, and 1 oz of cheese. kulahan and bigtunacan might say bok choy was my meal, but consistent with your observation, it provided only 9% of the calorie content.
