Snack biscuits are savoury biscuits that are often wheat-based. The most well-known products are crackers and pretzels. This category also contains croutons (Eastern Europe), extruded cereal products such as crackerbreads, and breadsticks (Southern Europe).
This is a sizeable market that is often focused on "health and wellness" offerings, as these products are not fried. There are also versions with additions, seeds, wholegrain recipes, gluten-free versions, etc.
