lunch n dinner can be rice n soup instead?
can cook like western style for him? like chicken chop/salmon steak/pork chop with mash potatoes/fries?
fried rice, fried beehoon, fried noodles.
noodles soup- kway teow, bee tai mak, beehoon.
can change the shape of the food. meaning if you giving minced chicken or pork, make into shapes of balls (like meat balls?) cut the veges (carrots, potatoes) into cute animals/shapes.
