Ingredients needed: whole wheatbreadtwo slices (available from bakeries),saladsauceone tablespoon, two salad leaves (lettuce can be used instead)Bitter gourdlettucecheese50 grams,cucumberone-third of a cucumber, half a teaspoon of salt.

Preparation: spread the salad sauce evenly on one slice of bread first.lay the washed salad leaves and cheese slices on one piece of bread;next, cut several thin slices of cucumber, arrange them on the other slice of bread, then sandwich them together.cut the remaining cucumbers into thick slices, sprinkle with salt and pepper, and place around the plate and beside the sandwiches.finally, bake in the oven for 15 minutes.This is made with cold-pressed bread,so it can be eaten while still warm upon removal from the oven. However, if using homemade bread that has been fermented, allow it to cool before consumption as high temperatures have not fully deactivated the yeast, which may contain carcinogens when consumed hot.Because the bread is baked, it can be eaten hot right out of the oven. However, if it's homemade and fermented, let it cool before eating, as there may still be traces of active yeast at high temperatures that could potentially contain carcinogens.
