Planning my own noodle dishes - check my math

Going for Hot/Sour taste

1. Glass Noodles - 0 sodium.
2. Black Vinegar (for sour) - NPG Baoning - 2mg per serving so basically 0
3. Momofuku Black Truffle Chili Crunch - 50mg per serving
4. Boil in Beef or Chicken no-sodium base - 0mg
5. Maybe Tamarind Paste - for sourness - 0 mg
6. Tom Yum hot sauce - 40-50mg per serving
7. Maybe add corn - there is no sodium canned sweet corn 0mg

Even if I use more than one serving of some things - still comes to like 200mg of sodium for the dish. Calories - probably 500-700 at most.

Does this sound way too low? I mean, my doc set the goal of "less than 1500". It almost seems like I will have to add salt manually not to go too low.
