In a large deep saucepan, combine ¼ cup (60g) water, the poblano pepper, and the salt and cook over medium heat, stirring occasionally, until the poblano begins to get tender, about 3 minutes.
Add the garlic and cook another minute. Add another splash of water if the pan is dry. Add the gochujang, tomato paste, coconut milk, and paprika and stir well until mixed thoroughly.
Add the chickpeas and lentils and mix well. Bring to a gentle simmer, then reduce the heat to low, cover, and cook until the sauce has slightly thickened and the chickpeas are tender, about 10 minutes. Remove from the heat and stir in the lemon juice. Taste and add more salt, if needed. (Brandi says, "I added another ¼ teaspoon.)
Serve as is, or add rice or a grain of your choice to the serving bowls. Spoon servings of the gochujang sauce over the top. Garnish with fresh greens.
