Hi! Some of the dietary preferences can't be combined because we don't have enough recipes to support the combination (at least not yet!). We're working on batch cooking, so that should help. Currently, it takes hacks to achieve that kind of thing (like adding more family members, e.g., Daniel, Daniel Leftovers, and Daniel Leftovers 2). If you have a slow cooker, you could select that in the appliances section and then just make sure that under time constraints, you select "more than 50 minutes" for dinners. Slow cooker recipes scale up well if you do that multiple family members trick. I hope that helps!
