Bring 1 cup of water to a boil. Add the bulgur and simmer, covered, until all the water is absorbed and the bulgur is tender (12-15 mins). Stir in the lemon juice3, scallions, jalapeno, 1 Tbsp. of the oil and 1/2 tsp. each salt and pepper.
Meanwhile, heat the remaining Tbsp. of oil in a large saucepan over medium-high heat. Add the onion and bell pepper and cook until tender, 6 to 8 minutes. Add the garlic, cumin, chili powder, 1 tsp. salt and 1/2 tsp. pepper and cook until fragrant, 1 to 2 minutes.
Add the tomatoes and their liquid, 1 cup of vegetable broth and 1 cup water to the onion mixture, bring to a boil. Add the beans and simmer, 10-15 minutes. Add kale - once kale has wilted, your soup is complete! Divide soup among bowls and top with the bulgur or serve on the side.
