Preheat the oven to 180 degrees, slice the onions into rings, and place them on a baking sheet. Sprinkle the onion rings with sugar and generously with salt and pepper. Drizzle with balsamic vinegar and olive oil and mix everything together. Roast the onions in the oven for about 30 minutes and let them cool.

Pour the red wine into a pan with the cinnamon, bay leaf, thyme, and sugar. Bring to a boil, peel the pears, remove the cores, and cut them into quarters. Place the pears in the wine and simmer for 10-15 minutes. Remove the pan from the heat and let the pears cool in the pan.

Slice the Boer'n Trots Peper Trio and mix it into the lettuce. For the dressing, mix all the ingredients well together in a small bowl. Toss the lettuce with the onions, pears, walnuts, and dressing, and serve with some parsley.
