Place the butter in a soup pot and allow to melt without browning. Add flour and stir to form a smooth paste. Cook the mixture over medium heat, without browning for 3 minutes, stirring constantly. Add the consume to the roux and stir until smooth and lightly thickened. Bring to a full boil. Add the fresh vegetables, tomatoes, and seasonings and allow to regain a boil. Reduce the heat and simmer until the vegetables are just barely tender. (This should take about 20 to 30 minutes.) Add the frozen vegetables and browned ground steak. Simmer an additional 15 minutes.
