Pat salmon dry of moisture with paper towel and season with salt and pepper to your liking
Salmon: Heat a non stick frypan/skillet on medium to high heat. Place salmon into pan, flat side down and cook for 4 minutes. Place a lid over to keep the steam in to help fish to cook through. Turn and cook other side for 4 minutes. Lid on.
Leeks and Lentils: Whilst salmon is cooking on the second side, heat a medium saucepan to high, add the butter, leeks, green beans and garlic. Stir with a spoon until the leeks become soft (around 3 to 4 minutes)
Once leeks are softened, stir through the chicken stock, lemon juice, Dijon mustard, salt and pepper, and cherry tomatoes.
Add the lemon zest, lentils and basil and stir through again. (See note 2)
To Serve: Place the lentil and leek mixture on the plate and place the salmon on top. Serve with additional wedges of lemon and diced basil.
Notes
Vegetable stock/broth can be substituted for the chicken stock/broth.
If you would like the leek and lentil mixture a little “looser” add a bit more water or stock and stir through until it reaches the consistency you are looking for.
