I was temporarily 'bujang' for the pass few days as my wife went outstation.
Soups, and noodle soups will be my choice if I cook for myself. My wife taught me the survival skills. I usually don't go for instant noodle for they're not healthy. Cooking a meal for one is simpe actually. Begin by preparing the soup base using drumsticks, mushrooms, dried oysters and all, and add the noodles once the soup is done.
Simple and nice (and nutritious too), enough to keep my stomach full.
