Cook your rice (instructions below).
In a large skillet over medium-high heat, add 1 tablespoon oil, veggies, and ½ tsp kosher salt. Cook until the veggies are tender, about 5 minutes, stirring occasionally. Transfer to a bowl and set aside.
While the veggies cook, in a small bowl mix together the peanut butter, vinegar, water, soy sauce, and syrup until combined (we’re adding curry powder separately). If too thick, stir in a splash of water. You want it to be easily pourable.
If making the cucumber topper, mix everything together in a bowl and let sit for 10 minutes.
Add the remaining 1 tablespoon oil to the skillet over medium-high heat along with the chicken and remaining ½ teaspoon salt. Cook, breaking it up into smaller chunks as it cooks, until cooked through, about 3-5 minutes.
Reduce the heat to medium-low. Add the veggies back into the pan along with the curry powder and cook for 30 seconds, stirring constantly, to toast the spices. Pour peanut curry sauce in and stir continuously to coat. Remove from heat.
Serve rice topped with chicken/veg, cucumbers (if using), peanuts, sriracha (if using), lime, and lots of basil and/or mint. If not using cucumber, be sure to squeeze with plenty of lime and add extra peanuts for crunch.
