In a large sauté pan over medium-high heat, melt the oil and add the onions, garlic and ginger with a big pinch of sea salt. Mix around for a minute, then lower the heat to medium and cook for another minute.
Chop the bell peppers (discarding the tops and the seeds) into thin strips and then cut the strips in half. Cut the carrots into thin circles. Add both to the sauté pan along with the curry paste and sugar, and cook for a few minutes. Now bring the heat to high and add in the coconut milk and water. Wait until the curry boils and then bring the heat down to a simmer. Let this cook for about 10 minutes, or until the veggies are tender.
Stir in the green beans, peas, kale, shrimp, mushrooms, cilantro and lemon juice. Cook until the shrimp are fully cooked through, about 2-3 minutes depending on the size.
Serve over quinoa or rice and top with fresh cilantro. Enjoy!
