Step 1

In a medium bowl, stir together the curry paste, fish sauce and sugar. In another medium bowl, combine 1 tablespoon of the curry paste mixture with the chicken, then toss until coated; let stand for about 10 minutes.

Step 2

In a 12-inch nonstick skillet over high, heat 2 tablespoons oil until barely smoking. Add the chicken in an even layer and cook, without stirring, until well browned on the bottom, about 2 minutes; the chicken will not be fully cooked. Transfer to the bowl with the remaining curry paste mixture; set aside.

Step 3

In the same skillet over high, heat the remaining 1 tablespoon oil until shimmering. Add the asparagus and onion; cook, without stirring, until browned on the bottom, about 2 minutes. Add the chicken-curry paste mixture; cook, stirring, until the sauce has thickened slightly and the vegetables are tender-crisp, about 1 minute. Off heat, taste and season with salt and pepper.

Step 4

Optional garnish: Chopped fresh cilantro OR basil OR lime wedges OR a combination
