Line a pot with a thin layer of water, bring to a boil, add kale, and cover for about a minute (the kale will turn bright green). Give it a stir so all of the kale is bright green and softer, then drain.
Mix in quinoa and/or beans to warm it up a bit, if desired. (I like to serve this with everything warm except the salsa, pineapple, and green onion, which are chilled.)
Transfer to a bowl and toss with salsa, pineapple, and green onions, leaving a few onion pieces for garnish. You can also drizzle hot sauce on top if desired.
