Add the oil or butter to your Instant Pot, then press the saute mode setting. Add the diced onion and saute for 2-3 minutes, or until translucent; add the minced garlic, and saute for another 30 seconds, until fragrant.
Then add the rice, soy sauce, and broth, and mix well, removing any brown bits on the bottom of the pressure cooker; this will help prevent a burn notice on your pressure cooker.
Set the rice option for 10 minutes, making sure that the vent is closed. If you do not have the rice option, set manual high pressure for 10 minutes. When the time is up, do a quick release, allowing all the remaining pressure to be released.
While your rice mixture is cooking, grab a skillet or frying pan, and over medium heat, add one teaspoon of vegetable oil or butter and scramble eggs for a couple of minutes. Before removing them from heat.
When all the pressure has been released from the pressure cooker, add the frozen vegetables and scrambled eggs and toss well. Garnish with sliced green onions or sesame seeds.
