Brown ground beef over medium-high heat, break into ½” chunks. Drain fat, return beef, sauté onion and pepper until translucent.

Layer stew: bottom beef + kidney beans with liquid, middle potatoes + celery, top diced tomatoes with juice. Add corn last 10 mins.

Simmer gently on medium-low heat 35 mins until potatoes fork-tender and broth thickens. Rest 10 mins before serving.

Optional: Thicken thin broth with cornstarch slurry, garnish with extra corn, parsley, and hot sauce.
