Remove any fat or gristle from the chicken, then cut it widthwise (against the grain) into strips no thicker than ¼-inch. Tip: Pop the chicken into the freezer for 10-15 minutes to make it easier to slice thinly.
Remove the woody ends of asparagus by holding one piece from both ends and gently bending the stalk. It will naturally snap where the woody bottom starts. Use this piece as a guide for where to cut the rest of the bunch. After discarding the ends, cut the asparagus into 1-inch chunks.
In a small bowl, whisk together the honey, garlic, soy sauce, lemon zest, lemon juice, and cornstarch until the cornstarch dissolves. Tip: Zest the lemon before juicing it.
Heat the oil in a large wok or skillet over high heat for 1 minute, or until glistening. Once heated, add the sliced chicken to the skillet and cook, stirring often, until browned and almost cooked through, about 2-3 minutes.
Add the asparagus to the skillet and cook, stirring often, for 2-3 minutes, until just nearly crisp-tender.
Quickly whisk the prepared sauce, then add it to the skillet. Cook, stirring constantly, until the sauce thickens and coats the chicken and asparagus. This takes about 1-2 minutes.
Serve immediately over rice, quinoa, or cauliflower rice if desired.

To make this chicken stir-fry gluten-free, use Tamari or your favorite gluten-free soy sauce for soy sauce.Leftovers: Store in an airtight container for up to 3 days in the refrigerator. Reheat in the microwave, covered with a damp paper towel, with a splash of water or soy sauce to prevent it from drying out.
