Which dish is described as a Texas style chili?

Texas-style chili is characterized by its bold flavors, focusing on meat (usually beef), spices, and often a rich, spicy tomato base, while typically avoiding beans, which is a hallmark of traditional chili in other regions. "Firehouse Chili" captures this spirit well, embodying the essence of Texas chili with its hearty ingredients and depth of flavor.

The other dishes listed do not align with the characteristics of Texas-style chili. Cajun Trout is a seafood dish with a Cajun seasoning influence, Baked Potato Soup is a creamy soup with potatoes and toppings like cheese and bacon, and Clam Chowder is a creamy soup featuring clams and potatoes, each belonging to entirely different culinary traditions. Thus, Firehouse Chili stands out as the dish most accurately described as Texas-style chili.
