Look up real ramen recipes and think about what each ingredient adds. Use other frozen veggies - a bag of stir fry mix can’t be that different from a bag of broccoli price wise. Eggs definitely. Sausage (or bacon, or Taylor ham, or Spam) can be a good flavor bomb. Frozen seafood mix adds protein, flavor, and changes the dish.

Also consider seasonings - any of the following help. Paprika, turmeric, garlic, onion, dill, bay leaf. Look at international noodle soups, adapt the flavors.

Oh, and you can also replace the packet seasoning with a low salt bouillion cube. Still a good flavor, but so much healthier. Mushrooms help too!
