Sauté the vegetables
Either pour the reserved chicken broth into a separate container and reuse the pot, or use a new pot. Heat 1 tablespoon of olive oil over medium heat. Add the diced onion, green bell peppers, celery, and jalapenos. Cook for about 10 minutes, stirring occasionally, until the vegetables are tender and golden brown.
Tip: If you want a milder soup, remove the seeds and membranes from the jalapenos before dicing.
Cleanup: Wipe up any oil drips around the stove with a damp towel once the vegetables are cooking.
