In a small bowl, add the maple syrup and the olive oil. Mix in the chopped rosemary.
In an 8x8-inch baking dish, add the chicken breasts and season with salt and pepper. Pour the maple rosemary sauce over the chicken and coat evenly.
Bake at 350 for 50-60 minutes, or until chicken has cooked through. Cooking times may vary slightly depending on the thickness of the chicken.
Just after putting the chicken in the oven, prepare the asparagus. Rinse and pat dry. Snap the ends off of the asparagus and place into the skillet. Drizzle with olive oil and season with salt and pepper.
Let marinate in the olive oil for about 30 minutes.
Then, saute for 4-5 minutes on high heat.
Prepare brown rice as directed on package. (If using plain brown rice, this can take 50 minutes! If using minute brown rice, it takes about 5 minutes!)
Serve Maple Rosemary Chicken with Asparagus and Brown Rice.
