While the potatoes are roasting, cook the lentils, prep the veggies, & make the dressing.
To cook the lentils, start by bringing the vegetable broth to a boil. Once boiling, add in the lentils and cook according to package instructions. If using the sprouted lentil mix I did, the lentils only need to cook for about 5 minutes.
While the lentils are cooking, chop the lacinato kale, slice the radicchio, and thinly slice the shallot. Then, add to a large mixing bowl.
Strain the cooked lentils and immediately add them to the bowl of vegetables while warm.
Then, make the dressing by adding the olive oil, lemon juice, dijon mustard, fresh dill, and salt to a glass and mixing together. Pour over the bowl of lentil kale salad and mix together. Let marinate until the potatoes are roasted.
