Combine seasoning with coconut milk and water in a wok over medium-high heat. Bring to a boil, reduce heat, and simmer for 2 min.
Add squash and lentils; cover and cook until tender, 7-10 min. Stir in snow peas, frozen peas, lime juice and soy sauce. Simmer until tender-crisp, 3-5 more min.
Serve over steamed rice or rice noodles, if desired.
