Cook the ravioli according to the instructions on the packet, set aside and let cool slightly in the stock.
Halve the lettuce hearts, remove the stalk and cut the leaves into narrow strips. Peel the pear thinly, cut into approx. 1 cm cubes and immediately drizzle with the lemon juice so that it does not turn brown. Peel the red onion, cut in half and cut into thin half rings.
Fry the bacon cubes in a pan until crispy.
Make a dressing from vinegar, oil, mustard, honey, salt and pepper. Combine lettuce, diced pear, chopped walnuts, onions and crispy bacon in a large bowl. Cut the still lukewarm Maultaschen into narrow strips, arrange on top of the salad and drizzle the dressing over them.
