Cook the pasta in approx. 5 l boiling salted water (1 teaspoon salt per litre) according to the instructions on the packet. Drain, rinse with cold water and let drain. Mix with oil in a large bowl and let cool.
Fry bacon in portions in a pan without fat until crisp. Take out and let it drain on kitchen paper.
Clean, wash and chop the peppers. Wash, halve and stone the peaches. Then cut into narrow slices and halve them crosswise. Leek onions clean, wash and in fine rings cut.
Peel garlic and chop finely. Mix yoghurt, barbecue sauce and garlic. Season to taste with paprika powder and a little salt and pepper. Mix the prepared ingredients except bacon with the sauce and the noodles.
Coarsely crumble the bacon and fold into the pasta salad shortly before serving.
