Sirloin Tips in Gravy
Add 1 tablespoon oil to the pressure cooker pot, select Browning. When oil is hot, brown the meat in small batches, do not crowd.
When all the meat is browned, put browned meat, onion and beef broth in pot, cover and lock lid in place.
Select High Pressure and 15 minutes cook time. (It will take about 15 minutes to pressure up and another 20 minutes for a Natural Pressure release.)
Gravy
Mix flour and water to make a slurry to thicken the broth. Add slurry to cooked meat and broth in pressure cooker pot.
Select Browning and bring to a boil. Boil for a few minutes until broth is thickened. Add salt and pepper to taste.
Stew
Heat sirloin tips in gravy, tomatoes, parsley and bay leafs until boiling over medium heat. Add diced potatoes and carrots.
Simmer until potato is almost tender stirring frequently. (Add water if necessary for desired broth consistency.)
Add macaroni. When the macaroni is almost done, add frozen corn. Serve when corn is heated through and potatoes and macaroni are tender. Remove bay leafs before serving.
