Sometimes, with stir-fries, you want the veggies, not the sauce, to be the star of the show. And in this recipe, you’ve got some major produce players: there’s bright and juicy bell peppers brimming with vitamin C, plus crisp sugar snap peas, which add irresistible crunch. So to let those veggie rock stars shine, we’re adding just a dollop of hoisin sauce for sweetness and umami depth, plus a healthy squeeze of lime to brighten things up and make this dish really pop.
