Salsa Sandwich

Serves 2 persons Ingredients: 4 tbsp olive oil (+ extra for greasing);3 large onions, peeled, in rings (or approx. 300 g ready-made onion rings);2 tsp dried thyme;6 hearty whole-wheat sandwiches (or brown casino bread);approx. 120 g extra mature (farmhouse) cheese, sliced/sliced;200 g cherry tomatoes, halved;1 tsp sugar;1 tbsp balsamic or other mild vinegar(tabasco or chilli powder) Preparation of the sandwich: Heat 2 tablespoons of olive oil in a non-stick frying pan and fry the onion rings with a pinch of salt and the thyme for 5 to 6 minutes on low to medium heat until brown and soft. Turn off the heat. Top 3 slices of bread with the cheese and spread the onion rings on top. Cover with the other slices of bread and press down firmly, making sure no cheese sticks out. If necessary, grease the frying pan with some extra olive oil and reheat on low heat. Fry the sandwiches over low to medium heat until brown and crispy on both sides, place a lid on the pan if necessary.Meanwhile, heat 2 tablespoons of olive oil in a wok. Stir-fry the cherry tomatoes with a pinch of salt, the sugar, vinegar and possibly a few drops of Tabasco or a little chilli powder for 1 to 2 minutes over high heat, until the tomatoes are soft and have released some liquid. Turn off the heat.Cut the sandwiches in half diagonally and divide between plates. Spoon some tomato salsa on each plate. Optionally, serve with a green salad.You can vary endlessly with cheeses, including foreign cheeses like camembert or emmental. Tomato ketchup is tasty, but this quick tomato salsa is even tastier and, along with the onion, you get quite a few vegetables in.And also try the delectable vegan version: replace the cheese with peanut butter and the vinegar and sugar with soy sauce manis. Any personal flavour additions, from banana to paprika to sambal, are of course welcome.
