How to Make It
Place coarsely chopped fresh cilantro leaves and stems, coarsely chopped white onion, garlic clove, and seeded jalapeño in a mini food processor; process until finely chopped and almost paste-like, stopping to scrape down sides as needed.
Heat olive oil in a large skillet over medium-high. Add fresh cauliflower crumbles or riced cauliflower (about 4 cups); cook, stirring occasionally, 3 minutes. Stir in cilantro mixture; cook, stirring occasionally, 2 minutes or to desired texture. Stir in fresh lime juice and kosher salt.
