I eat way too much ramen, so I have several favorite tweaks - but I leave in the original spice packet for all of them.
Chicken Flavor Ramen: (always add in leftover chicken if there is any in the fridge)
One: add about 1/4 teaspoon of peanut butter per packet, fish sauce to taste, and of course the chile powder of your choice. This is really good, it makes the dish feel a bit more hearty. Of course adding real food, like meat and veggies would make it more of an actual meal.
Another: Add coconut water in as a substitute for some or all of the water to boil the noodles, then add curry powder, and the chile powder of your choice. Makes it sort of like a thai curry.
Egg drop: Add an egg, some ginger powder, and chile powder or sauce of your choice. The egg absorbs lots of flavor so this one ends up a bit more bland unless you use a flavorful hot sauce or some soy sauce etc to liven it up.
Beef Flavor Ramenalways add in leftover beef if there is any in the fridge)
Chile powder, black pepper, cumin,
