Thai Lime Coconut Chicken (or vegetables)

Ingredients:
1 lb boneless, skinless chicken breasts, cut into 1-inch cubes (see below for vegetarian substitution)
1 TBSP olive oil
3 cloves garlic, minced
1/2 yellow onion, sliced
1 tsp curry powder
1 14 oz can light or regular coconut milk
Zest and juice of 1/2 lime (use a 1/4 lime zest and hand squeeze half a lime, otherwise it's too limey)
1/4 cup green onion, chopped (optional)
2 tbsp fresh cilantro, chopped (optional)

Directions:
Heat the oil in a large skillet over medium heat.  Add the chicken, garlic, and onion and cook chicken until golden brown on all sides, about 5 minutes, stirring frequently. Add the curry powder and cook, stirring for 1 minute, until it is fragrant. Add the coconut milk, lime juice and zest, bring to a simmer, and simmer until the chicken is just cooked through, about 5 minutes. Season to taste with salt and pepper. Remove from the heat, stir in the green onions and cilantro.  Serve over rice.

For vegetarian/vegan, replace the chicken with the following:
10 baby golden yukon potatoes, cut in 1-inch cubes
12 baby carrots, sliced
