I've heard these called a couple of different names but in our family we call them Hawaiian Haystacks. These are delicious, filling and fun to eat and make.
Rice, cooked (enough for your family)
Chicken gravy (recipe here)
Plate your rice and cover with gravy. Add any or all of the following according to your personal preference:
chow mein noodles
pineapple tidbits, drained
mandarine oranges, drained
green onions, chopped
green pepper, chopped
cheddar cheese, shredded
frozen green peas, rinsed
I usually just have little dishes of the individual ingredients on the table and let my kids make them how they want to.
