*Recipe yields 10 medium size meatballs. *Egg and Oats flour is important for meatball binding, do not skip it. *I used instant / quick oats , then grinded in the food processor into fine powder. You can also use readymade oats flour instead. *Just soaking the soya chunks / soya granules in boiling hot water is enough for this recipe. ( need not boil and cook chunks completely in hot water, it will anyway be fully cooked while pressure cooking). *Water and pasta sauce measurements are only given for 4 oz spaghetti , if increasing the quantity of spaghetti, then double the quantity of water , and sauce. *I used thin variety spaghetti's , but if you use a thick spaghetti , then I suggest you to increase the pressure cooking time . *Other Instant Pot Recipes , All recipes are given with step by step pictures , tips, and detailed instructions.
