• The lasagna block gives you a bowl back when the block runs out, but has no bowls in its recipe
• the hot dish block gives you a bowl back, but needs 2 to be crafted
• The salad block doesn't seem to be interactable with a bowl, is there something else that you need to do to get a portion?
• ALL the feast blocks can be broken be a single accidental punch, and only give you an empty bowl even if the block is full. By comparison the FD feast blocks will give you the block item back if you haven't taken a portion yet
• the Portion-taking recipe is untranslated
  

Finally, just a couple notes

1. Are you sure you need two output slots on your Oven when your recipes won't run without a container in the container slot anyway? Every recipe just immediately moves to the last output if its empty
2. My suggestion is to model it after FD's cooking pot, and let some recipes work if there is no container (but maybe not the bulk ones that need the sheet), and just have them sit in the second last slot until the right container is provided
3. I also think it would be cool if the feast blocks that use the square pan actually took it, and gave it back when you're finished with the food block. Essentially using it a metal bowl. I don't know how you'd handle a partially damaged pan though, so I can see how it might not be in your interests.
