These taste great and freeze well. I reheat them in the microwave, slice them in half and put them on a biscuit, English muffin, or toast  to make a breakfast sandwich. 
You will need an Instant Pot with a trivet, and silicone egg bite mold(s) for this. Egg bite molds can be found here: 
Amazon Instant Pot Silicon Egg Molds

1. Spray the silicone egg bites mold with the cooking spray. Set aside.
2. Several methods for mixing the ingredients and filling the molds: 
   1. Put all ingredients (except the water) into a bowl and mix with a mixer until the mixture is light and fully incorporated. With this you just spoon everything into the mold at once.
   2. Some directions suggest leaving the meat out during the mixing process, filling the molds halfway with egg mixture, adding the meat, and then topping off the molds with the remaining egg mixture. 
   3. I have also had success with mixing the egg and cream mixture with just the seasonings, cheese, & chives, and putting the rest of the stuff in the bottom of the molds. Then I put a little of the egg mixture in, stir it all up with the other ingredients, and then top it off with more egg mixture.
3. DID YOU REMEMBER TO SPRAY THE MOLDS WITH COOKING SPRAY??? If not, dump the stuff back in a bowl and SPRAY THE MOLDS!!**
4. Some people say fill them 3/4 full, but I do them within an 1/8" of the top. Your option.
5. Pour 1 cup of water into the inner stainless liner of the pot.
6. Set the full egg bites mold on a trivet and very carefully set it in the pot. I loosely covered it with the lid that came with the mold. Or you can use foil. Not sure there is any point to covering them really. (I only do one mold at a time; some people do two molds and stack them somehow.)
7. Close the lid of the pot and set the steam release knob to the Sealing position.
8. Press the Pressure Cook or Manual button (or dial) then set for 8 minutes.
9. The pot will take a few minutes to come to pressure.
10. When the cook cycle is finished, let the pot sit for 8 minute Natural Release.
11. Then open the steam release valve to release the remaining pressure until the pin in the lid drops down.
12. Open the lid.
13. Carefully remove the egg bites mold using the trivet handles.
14. Set aside to rest for about 4 minutes.
15. They may be puffed up quite a bit, but they will go back down.
16. Pop them out of the mold and enjoy, or freeze for later.
