We've been eating a lot of quinoa cooked this way lately. It basically goes well with anything that you'd serve with rice, and I think it both tastes better and more interesting than rice.
You can leave out the lime juice and lime zest if you aren't going for a limey effect, but do toast the quinoa first to enhance the flavor, and use the salt and butter. I haven't actually made it with the lime to go with the lentils, usually I add that if it's more of a stand alone side dish because citrus is awesome.
Instant Pot Lime (or Not) Quinoa

Place quinoa in pot of Instant Pot and set to saute. Stir frequently until quinoa is lightly toasted, about 5 minutes. Add butter and stir until melted. Add water, lime juice, and salt. Stir. Turn off Instant Pot, then set to Manual for 1 minute. Seal. Do a 15 minute natural pressure release, then unseal, fluff, and serve.
