Chili garlic sauce can be found on the international aisle of most supermarkets. Add to stir-fries or marinades, stir into ketchup for a spicy kick, or top scrambled eggs.
Heat a large skillet over medium-high heat. Add 1 tablespoon oil to pan; swirl to coat. Add bell pepper and Broccolini; cook 5 minutes or until crisp-tender, stirring occasionally.
Combine remaining 1 tablespoon oil, vinegar, and remaining ingredients in a small bowl, stirring with a whisk. Drizzle vinegar mixture over Broccolini mixture; toss to coat. Serve immediately.
