In a medium saucepan, bring 5 cups chicken stock to a boil. Add sage, 1/2 teaspoon pepper, 1/2 teaspoon garlic and wild rice. Cover, lower to a simmer, and cook for 10 minutes.

Add long grain rice and cook for an additional 30-35 minutes, stirring periodically to check that you still have water. You want your rice to just be tender. Test it at 40 minutes.

Meanwhile, dice and chop the onion, celery, carrots, broccoli, and mushrooms. Heat a large kettle with ½ to 1 tablespoon of olive oil. Add the vegetables (except the mushrooms) remaining garlic, salt, pepper, sage, and thyme, cooking on a medium heat for ten minutes.

Add mushrooms and cook for an additional five minutes. Remove the vegetables from the kettle and place them in a large bowl.

In the same pan, add an additional 1/2 tablespoon olive oil and cook the ground venison (or hamburger or turkey) until no longer pink. Stir into the bowl of vegetables along with cooked rice.

In the same kettle, melt the butter under medium-low heat. Stir in flour and continue to stir until you have a beautiful golden brown color. To this, add milk, 1/4 of a cup at a time, whisking until well combined and thickened. Repeat with the remaining chicken stock. Pepper to taste.

Stir in to the vegetables, rice, and browned venison. Taste once more, adding salt and pepper as needed.

Spread the mixture into a greased casserole dish and bake uncovered for 20 minutes at 425 degrees, until just crispy on the top and hot all the way through.
