Put your white beans to water a night before to let it rest about 12 hours or more. (If you add 1-2 pinches of baking soda to washing water your beans will be more delicious.)
Heat your 4 tbsp. of vegetable oil in pressure cooker. Add 1 finely chopped onion and stir it until tender.
Add 250 gr. (0,6 lb.) meat to your onion, cook about 3-4 minutes stirring occasionaly.
Put your 1 full tbsp. tomato paste, stir a few couple times.
Add your 3 cup rested white beans, stir a couple time more.
Add your 3 cups of water to pressure cooker.
Add your 1 tsp. of salt and wait until it boils.
Cover your pressure cooker when it boils. It will take about 15-20 minutes after the cooker starts to whistle and your White Bean Stew with Meat will be ready.
