Wash the beets well, then trim off the root and the leafy tops.
Pour 1 cup of water into the Instant Pot. Place the beets in a steamer basket and set it inside. No basket? Place a trivet inside and set the beets on top.
Close the lid, set the valve to Sealing, and cook on High Pressure for 15 minutes.
Allow a natural pressure release for 10 minutes, then manually release the remaining pressure.
Open the lid and allow the beets to cool. Once cool, the skins will slide off easily by rubbing with a paper towel.
While the beets cook, soak the red onions in a small bowl of cold water mixed with ½ teaspoon salt. This removes their sharp bite and makes them sweeter.
In another bowl, mix lemon juice, crushed toasted cumin seeds, salt, and olive oil. Let this dressing rest while the beets finish cooking.
Once the beets are cool enough to touch, peel and cut them into 1.5-cm wide wedges.
Toss the warm beets with the dressing, add the drained onions, and mix well.
Finish with fresh mint and parsley (or cilantro).
Serve warm or at room temperature with your favorite meals.
