Do you use a gigantic mixing bowl for your salad? Do you have a favorite plate - pretty color, nice shape, just the right size? do you use measuring cups, or something else to portion out your food? Does just the right place-setting make you happier with your meal? Do you think using a smaller plate (ala behaviour modification) helps you to eat less? Do you use different dishes than the rest of the family? Answer as many as you like, or add something!
Years ago, I bought a green plate made by Homer Laughlin (of "Fiesta" fame) at a thrift shop. My plate has a nice scalloped edge and it is smaller than a regular dinner plate. The medium green color goes well with my food, and my plate makes me happy with my meal. I have a little cobalt blue ramekin that holds exactly 1/4 c. I use this to serve myself nuts or snack mix. I love the color and the snack makes me happier in the blue dish than just using a glass custard cup.
My DH bought our dogs gigantic stainless salad bowls for their meals. They chewed up all their other dishes. These dishes make the dogs happy.
