I had a lentil mix, and it cooked for just 15 mins, so the lentils were al dente. You do it with some diced celery, onion and carrot. Once drained and cooled toss with a dressing of lemon, olive oil, salt and pepper, and some raw diced crunch veggies of oyur choosing. Parlsey would be good too. And a little fresh raw garlic if that is your thing(I love garlic).
Let me try to find the basic recipe i toyed with. BRB.
It was this:

Tomato would be good, if you had a good one, really anything, like you migh tdo with a rice or quinoa salad. They take on what you use flavor them. never used red ones alone, so just do not overcook, since they can turn to mush.
if you decide to go for a soup, i have a good lentil spinach soup recipe.
