Lentils cook fast … and tinned lentils cook even faster, ideal for a supper for one!
I gently sautè finely chopped onion, carrot and celery in olive oil. When cooked, I add some chilli flakes and a good squeeze of tomato concentrate diluted in a little water. Then I add the tin of lentils and salt, and heat through.
This is nice with some toasted bread and/or some feta cheese crumbled on top.
