This Texas-style ground beef and rice casserole is a hearty and flavorful dish that is perfect for a family dinner. It combines ground beef, rice, tomatoes, and spices to create a delicious one-pot meal. The beef is browned and then simmered with onions, garlic, and bell peppers before being mixed with cooked rice and tomatoes. The casserole is then baked until the flavors meld together and the top is golden and crispy. Serve this comforting casserole with a side of cornbread or a green salad for a complete meal.
