Make the sauce. In a small bowl, whisk soy sauce, fish sauce, honey, rice vinegar, chili paste, water, and cornstarch (if using).
Set aside.
Prep the veggies. Dice the onion, mince the garlic, slice the chilies and bell pepper, and cut the green beans. Pick basil leaves from stems.
Cook the green beans. Heat a large skillet or wok over medium-high. Add 1–2 teaspoons oil and sauté green beans with a pinch of salt for 3–4 minutes until crisp-tender.
Transfer to a plate.
Brown the chicken. In the same pan, add remaining oil. Add ground chicken and cook, breaking it into small pieces, for 5–6 minutes until lightly browned and no longer pink.
Add aromatics. Stir in onion, garlic, and sliced chilies. Cook 2–3 minutes until fragrant and slightly softened.
Add peppers and beans. Return green beans to the pan and add red bell pepper.
Toss for 2 minutes to heat through.
Pour in the sauce. Stir the sauce and add it to the pan. Cook 1–2 minutes until it lightly thickens and coats the chicken and vegetables. Adjust seasoning with extra soy, chili, or honey if needed.
Finish with basil. Turn off the heat.
Fold in basil leaves until just wilted. The residual heat keeps the flavor bright.
Assemble bowls. Divide cauliflower rice (or your preferred base) among four meal prep containers. Top with equal portions of chicken and veggies.
Garnish with green onions and lime wedges if you like.
