Parboil pasta until it is a bit firmer than al dente (2 mins less than on pack, it will cook more in the oven) once it’s cooked, drain and leave to dry out for a couple of minutes before stuffing.
Set oven to heat to 200 C/ 350 F
Finely dice peppers, onion and mushrooms
Fry onion and garlic first, then add the pepper, mushroom and chilli
Add tinned tomatoes and cook off some of the liquid
Cut up and add sun-dried tomatoes and lentils. Mix well. You now have the stuffing for the pasta.
Stuff pasta shells with sauce, then add the rest of the sauce on the top
