Both my grandchildren love nuggets but the eldest is not too good with cauli unless it is smothered with cheese sauce. Growing boys need as many veges as possible to ensure strong bones and teeth. His little sister loves cauliflower!
With our grandson, 7, we make muffins together with fruit as an addition and for the veges add them to his mashed potato, which he adores! For dinner when we want him to try a new vege he will have pieces, small, the same number as his age.
