Preheat oven to 375°F (190°C). Cover a baking plate with parchment paper. Set sausages and oven-bake for 15 to 20 minutes until sausages are entirely cooked or roasted. Cool down. Slice sausages in two over its length then chop.
In a large casserole, fry at medium high heat leeks and mushrooms in olive oil for 5 to 10 minutes until mushrooms tender and leeks roast. Add chopped sausages and mix well. Soak with broth, add barley and bring to a boil. Lower heat and simmer at low heat until barley is cooked, about 30 minutes. Season.
