In a large pot, brown the ground beef over medium heat until fully cooked. Drain excess fat.

Add chopped onion and minced garlic to the pot and sauté until softened.

Stir in chili powder, cumin, salt, kidney beans, diced tomatoes, and water. Bring to a boil.

Reduce heat and let simmer for about 20 minutes, stirring occasionally.

While the chili is simmering, grill or boil the hot dogs according to package instructions.

Place each hot dog in a bun and top generously with chili.

Sprinkle with shredded cheddar cheese, chopped onions, and jalapeños if desired.

Serve immediately and enjoy!
