Cook sausages by grilling or pan cooking over medium-low heat until done. Cooking time depends on the type of sausages you use: Chicken will average 15 to 20 minutes; Pork 20 to 30 minutes.
Sweet Potato Mash
Place peeled and diced sweet potatoes in a pot. Cover with water and bring to a boil. Reduce heat to a simmer and cook potatoes until soft. Do not overcook or they become soggy.
Using a colander, drain sweet potatoes. Do not reserve water.
Return potatoes to the pot and mash until smooth using a potato masher or fork.
Pour in olive oil, mix well and season with salt and pepper. Adjust taste as needed.
Mushroom and Leek Herb Gravy
Heat olive oil in a large skillet over medium-low heat. Add leeks and mushrooms, sautéing gently until softened before adding minced garlic.
Add white pepper, garlic powder and flour. Stir flour constantly, cooking for about two minutes.
Slowly start pouring in beef stock and milk, stirring constantly to keep lumping from forming. Continue to stir constantly, bringing gravy to a simmer. Continue to simmer and cook until gravy reaches desired thickness.
Add fresh basil, rosemary and thyme. Season to taste with salt and pepper.
Remove gravy from the heat and use immediately.
Bangers and Mash Assembly
Place a portion of mash on plate. Top with a sausage and then pour gravy over both.
Serve and Enjoy.
Can also use roasted sweet potatoes for the mash for even more flavor.
