If youโre looking for a way to use up the leftover beef from your roast dinner, give this warm beef and lentil salad a go.
Itโs simple to make (perfect if you donโt have the time for a Leftover Beef Cottage Pie) and you can use up the bits and pieces that are leftover from your roast.
It has a delicious honey mustard dressing that goes PERFECTLY with the beef, and the lentils and salad are light enough if you donโt fancy something really heavy after your indulgent meal.
This is protein packed and so tasty โ in fact, if you prepped this at the weekend after your dinner, it would make fantastic lunches throughout the week (you can eat it cold, too).

The Ingredients
- Baby carrots โ I love little baby carrots and think they give any dish the โwowโ factor. However, you absolutely could use normal carrots. Just cut into bite size pieces. You could also use leftover roast carrots from your Sunday roast, just warm up in the oven rather than roasting as per the recipe.
- Leftover roast beef โ cut your beef into bite size chunks and heat in the oven until sizzling for this salad. If you donโt have any leftover roast beef and still want to make this salad, just fry up some stir fry steak and use that.
- Cooked puy lentils โ as a get ahead when Iโm busy, I like to use pouches of microwaveable puy lentils. They take a minute to heat up in the microwave and are perfect for this recipe.
- Salad leaves โ use any you like. Peppery ones work well โ I used a selection of watercress, rocket and spinach.
- Runny honey, English mustard, red wine vinegar and olive oil โ these ingredients make your sweet, spicy, sharp dressing and it works BEAUTIFULLY with beef.

Top Tips
- Use your leftovers This is a flexible recipe โ you can add in many of your leftover meats and vegetables. It also works well with leftover chicken instead of (or as well as) beef.
- Get ahead This is a perfect recipe for prepped lunches. When youโve had it warm the first time, store in the fridge and eat chilled after that. It will be good for 4 days.
- Cooking the beef Because we are reheating leftover beef here, itโs important to cook it through โ so if you had pink roast beef, it will be browned here. Itโll still be delicious though!
