Warm up a good-sized saucepan. Melt the butter together with olive oil, then toss in the celery chunks. Stir it around for a few minutes until it starts softening up.
02 -
Drop the chopped garlic and lentils into the pan. Stir them for about 1-2 minutes, letting the lentils get coated in the buttery mixture.
03 -
Add your stock to the pan and bring it to a gentle bubble. Toss in cheese rinds now if you're using them instead of grated cheese. Pop on a lid and let it cook for 20 minutes or so, until the lentils soften up and start falling apart.
04 -
Add the broccoli or any veggie choice to the pan. Let it simmer for another 5-10 minutes until those veggies are nice and tender.
05 -
Take the soup off the burner. Use a stick blender directly in the pot to blend it all together until smooth. Or, if you prefer, pour the soup into a jug blender instead. Make sure to leave an opening for steam to escape by removing the center bung and covering the space with a towel.

If the soup feels too thick, slowly work in some extra hot stock until it's the way you like it. Stir in the grated cheese and wait for it to melt and mix well.

Give the soup a taste, then throw in salt and pepper as you like. Serve it steaming hot, and crusty bread works great on the side.
