In a saucepan, combine the soy sauce, water, ginger, garlic, brown sugar, and honey, and begin heating over medium heat.
Bring to a simmer and allow to simmer for approx. 3 minutes.
Mix the cornstarch and cold water in a cup until the cornstarch is dissolved.
Add to saucepan.
Reduce heat to medium-low.
Heat until the sauce thickens to your preference.
If it's too thick, you can add water to thin it out.
Set aside and allow to cool.
Once cooled to at least room temp, place the salmon fillet into a large freezer bag. Add half of the teriyaki sauce and shake it up. Allow to sit for 20-30 minutes for a quick marinade.
SALMON/VEGGIES/NOODLES
Preheat the oven to 425 degrees F.
Bake salmon for 10 minutes, or until tender and flaky.
While the salmon bakes, prepare the instant Ramen noodles as per the package's instructions.
Steam the broccoli, bell pepper, and water chestnuts for approx. 7 minutes or until tender.
Drain the noodles when ready, and place into a large bowl.
Drizzle some of the remaining teriyaki sauce onto the noodles and toss to coat.
Add the steamed vegetables.
When the salmon is ready, flake into chunks and add to the bowl.
Toss everything to mix.
Serve and garnish with sesame seeds if desired.
Notes
If you're strapped for time and don't want to marinate the salmon, simply drizzle the salmon with some teriyaki sauce before baking it and baste it every five minutes until done.
