These noodle bowls are delicious with chicken, but see the notes for ways to make them with shrimp or veggies! You can use any kind of curry powder or paste for this dish. I always recommend starting small and then adding from there, especially since different brands carry different levels of heat. Many grocery stores carry a fairly mild yellow curry powder that's a good place to start, though you can turn up the heat or change the flavor by swapping red curry paste or green curry paste.
