Green vegetable curry

Cook beans and broccoli in a large pot of boiling water until almost tender, 2 to 3 min. Drain and plunge into a large bowl of cold water. Drain and pat dry. Cut peppers into 1/4-in. strips. Cut tofu into 1/2-in cubes. Heat oil in a large pot set over medium-high. Add curry paste or powder. Stir constantly until fragrant, about 1 min. Add peppers and onions, then tofu. Stir until evenly coated. Cook for 1 min. Pour in coconut milk. Gently stir in fish sauce and sugar until evenly mixed. Bring to a gentle boil. Simmer until thickened, 3 to 5 min. Add broccoli, beans and spinach. Cook until vegetables are hot, about 2 min. Stir in lime juice and cilantro. Serve over steamed rice. Cover and refrigerate curry for up to 5 days.
