why my dishes are always over satiating?
"Too delicious, and you can't eat more of it": 

I don't see the "too delicious" part as a problem. Delicious is good.

"Can't eat more of it", as others have pointed out, sounds like it is just too heavy, or too rich. So, as others have also pointed out, it might help to cook some less heavy foods. In general, fish, tofu, and vegetables (especially raw or steamed) tend to be lighter and less filling than meats and heavy cheesy or buttery sauces.

Depending on your cuisine tradition, however, substituting different food items may not be an appealing option. If most of the dishes that you and your family find acceptable happen to be on the heavy side, at least you can serve them along with other things in the meal to add variety, like plenty of plain rice or other simple grain, green salad, and/or steamed, pickled or raw vegetables and maybe a refreshing cold beverage or fresh fruit.
