  • 1/2 cup milk dairy or non-dairy

Instructions

  • Heat Instant Pot using saute and add oil. Add onions and cook until translucent (about 5 minutes)
  • Turn Instant Pot off, add the egg noodles to the Instant Pot
  • Pour vegetable broth over and around noodles
  • Place tuna and broccoli over noodles and season with spices

Notes

I use either Daiya or Violife shredded cheddar style for the non-dairy cheese and whatever non-dairy milk I have on hand (make sure it’s unflavoured).
