Turn heat down to medium-high and add remaining oil to pan. When hot, add cumin seeds (if using), fry for 30 seconds, then add onion and potatoes. Add garam masala, along with 1/4 teaspoon salt and cayenne pepper. Cook, stirring or tossing, until onion has caramelized and potatoes are lightly browned, about 10 minutes; potatoes need not be fully tender.
Return chicken to pan along with snow peas and continue cooking and stirring for about 2 minutes, or until chicken is warmed through and snow peas are crisp-tender. Taste, adjust seasoning, and serve garnished with cilantro or mint and lime wedges.
- You can always substitute other spring vegetables for the same effect, such as asparagus, spinach, or broccolini.
- Stir-fried potatoes are a fast way to get potatoes on the table. They should be thoroughly cooked but a little crunchy from frying quickly. A little like hash browns.
- To make this vegetarian, substitute tofu cubes for the chicken or use up to a cup of shelled peanuts. Choose peanut or grapeseed oil here so you can get it hot without too much smoking. If neither is available, use canola oil.
