Start by cooking your vegan chicken strips according to the package directions. When done, chop up into bite-sized pieces and set aside.
Get a large pot and melt the butter, add the chopped onion and cook down for about 5 minutes; add the rest of the vegetables, fresh garlic, seasoning, and stir. Add broth and water. Let this cook together for 15 minutes at a low boil.
Add your noodles and cooked chopped-up vegan chicken strips, bring to a simmer and let simmer for around 10 minutes; this will depend on the type of noodles you use. You may need to decrease this time; your noodles will still cook when removed from the heat, so account for that.
