Preheat your oven to 400°F (200°C) and prepare the Brussels sprouts by washing them before slicing each one in half. Line a baking sheet with parchment paper and spread the halved sprouts on top. Drizzle with olive oil and season generously with salt and pepper, then toss everything together until evenly coated. Roast in the preheated oven for 20 minutes.
To make the aioli, combine Huy Fong Sriracha Sauce, sesame oil, Duke's mayonnaise, Thai Kitchen Sweet Chili Sauce, and lime juice in a medium bowl. Whisk until all of the ingredients are well incorporated. Once the Brussels sprouts have finished roasting, transfer them into a large mixing bowl and pour the aioli mixture over top. Toss to evenly coat each piece.
Serve your warm, roasted Brussels sprouts slaw garnished with freshly chopped cilantro, mint leaves, lightly toasted cashews, and lime wedges for an extra zesty flavor.
