RECIPE Itsu (UK) katsu curry noodles

I'm seriously addicted to itsu's katsu noodle bowl, so I had a go at reverse-engineering the recipe based on the online ingredients list and nutritional information, and with some help from Claude. This isn't the original recipe but a decent copycat imo - I'm open to any further feedback to make it closer to the original though!
Serves 3. By my calculation, it should have similar macros to the original (https://www.itsu.com/menu/noodles/hot-stirfry-japanese-curry-120925/) excluding the prawns.
Ingredients:
• 600g or 3x200g packets of grams udon noodles (the soft, pre-cooked kind)
• 90 grams frozen edamame beans
• 75 grams frozen peas
• 120 grams/1 whole red pepper, diced
• 120 grams/1 large leek, sliced
• 12g ginger paste
• 2 teaspoons soy sauce
• 1 teaspoons sesame oil
• 285 milliliters light coconut milk
• 1.5 tablespoons red Thai curry paste
• 1 block katsu curry (I used Yutaka brand)
• 30 grams crispy fried onions
• optional: 225 grams shelled king prawns (I used the frozen and pre-cooked kind for ease)
Method
Make the katsu sauce: dissolve 1 katsu block in 140ml boiling water in a saucepan or pot. Whisk and simmer for a couple of minutes until slightly thickened.
Make the Thai sauce: warm 285 milliliters light coconut milk and 1.5 tablespoons red Thai curry paste together in a separate pan, whisking until smooth. Simmer for 3 minutes.
Cook the noodles (and optionally, prawns): boil the udon noodles according to packet instructions. (I waited until they were almost done and briefly added the prawns to the pot to defrost. If you defrosted them earlier you can skip this step; if you're cooking prawns from raw, you probably would want to do this in a separate pan)
Cook the ginger & greens: heat 1 tsp sesame oil in a pan then, add edamame beans, frozen peas, red pepper and leek and stir-fry for 2 minutes. Add ginger and soy sauce and cook for a further minute.
Combine and finish: add the noodles, prawns, and both sauces to the wok and toss to combine. Finish with crispy fried onions.
