Cook your pasta of choice, reserving the cooking water before draining.
Preheat the oven to 185C.
Add a large red pepper (sliced in long strips), onion (sliced in half), tomatoes and half a head of garlic to a baking tray . Drizzle with a good glug of olive oil, black pepper and a pinch of salt. Toss well with your hands until evenly coated.
Pop the tray to bake for 30 minutes or so until the veggies are softly-charred and tender.
Once the roasted veggies have cooled down, add them to a blender jar, squeezing out the caramelised garlic cloves. Add the feta and 2-3 tbsp of olive oil, along with a splash of the pasta cooking water. Blitz until smooth.
Gently warm the sauce up in a large pan. Stir in tomato paste, seasonings of choice (paprika; chilli flakes etc) and cream.
Toss in your pasta, mixing well. Add more pasta water/ cream depending on your desired consistency. More pasta water will thin down the sauce, while more cream will thicken it with a creamy consistency.
Serve with fresh basil and crumbled feta
