In a medium saucepan, combine the lentils, garlic, cumin, coriander, red pepper flakes, black pepper, and 2 cups of water. Bring to a boil, reduce the heat to low, cover, and simmer for 20 minutes, or until the lentils are tender.
In a large skillet, heat the olive oil over medium-high heat. Add the onion and bell pepper and cook for 5 minutes, or until softened.
Add the vegetable broth, white wine, and lemon juice. Simmer for 5 minutes, or until the liquid is reduced by half.
Add the cooked lentils, parsley, and kale. Cook for 5 minutes, or until the kale is wilted. Taste and add salt, if needed.
