When the tomatoes are almost done, heat the remaining olive oil in a large stock pot over medium heat. Add the chickpeas and cook, stirring often, for 30 seconds until just crisped. Add the spices: paprika, pepper flakes, fennel seeds, mustard, garlic powder and remaining salt and pepper. Toss until beans are completely toasted and spices are fragrant, about 2 minutes. Stir often, taking care not to burn.
