Whether it be to vary the pleasures, to avoid gluten or to limit carbs, replacing a sandwich bread with a vegetable is easy and fun. The proof 5-fold!
Cucumber
Cut in half and emptied of its gains: fill it with fresh cheese, smoked salmon or crudités instead of a French baguette, it makes everything fresher!
Baguette, bagel, burger and triangles of sandwich bread will always be happy to welcome lettuce, zucchini, button mushrooms, aubergine and cucumber in slices... if not to cede their own place from time to time!
