(Optional) Cook bacon whichever way you feel most comfortable that will give you bacon crumbs. I prefer to cut them crosswise with kitchen shears and spread the pieces on the baking sheet to bake at 350 F degrees for 30 minutes.
On Instant Pot, press the sauté button and allow to warm up. When 'hot' is displayed on the screen, add cooking fat and chopped onions. Cook until translucent, stirring occasionally.
Add ground meat, garlic and all spices. Continue to sauté , breaking up the beef until it's almost fully cooked and all the spices are incorporated.
Bacon should be done by now, if using. Remove it from the oven and reserve the fat for other uses.
Add chopped potatoes and cooked bacon to the ground beef mixture directly into the Instant Pot.
Add enough broth or water to the 1.4L (3 quarts) mark and give it a quick stir.
Close the lid, set the valve to sealing position and set to manual for 4 minutes cooking time.
When the cycle is complete, do quick pressure release until safety pin is completely down.
With caution, open the lid, add chopped kale and cream. Give a quick stir once more and season with salt if needed.
You can close the lid back and keep it set to Keep Warm until ready to enjoy. Garnish with extra parmesan just before serving.
