Vilgain Shiitake Hazelnuts Quinoa

Hello, I am intolerant to gluten, lactose, nuts, garlic would it be possible to make a version without hazelnuts? I buy a similar product from migros. https://www.migros.ch/de/product/157230700000 which contains Cooked quinoa 77% (water, white quinoa * 37%), vegetables 20% (corn * 25%, red pepper * 25%, peas * 25%, carrots * 25%), sunflower oil *, basil *, natural flavor, sea salt, cornstarch.

Should I pour 900ml of water into one serving?
