Some foods lack the nutritional value like shepherds_pie, honey_glazed_ham and stuffed_pumpkin due to, what I'll assume, their uncommon crafting mechanic.

looking at the mod's tags I see there's already said compat but it doesn't seem to work in my instance, so I'll report this as a bug instead of suggestion.
Tested with FarmersDelight-1.18.1-1.0.3, nutritionalbalance-1.18-3.0.1 and forge 39.0.63

Fix has been released in the 1.18-3.0.2 version. It turns out Minecraft changed how item tags work which is why this wasn't working.

Thanks for reporting this! I added Farmer's Delight support when this mod was first released back in 1.16.5. Something must have changed since then.
