Match your use: for sandwiches, pick pizza dough; for dippable open-chew, pick ciabatta dough; for instant warm bread, pick naan or pita.
Swap by quantity using the listed ratio (use equal dough/bread mass/loaf portion as the starting point).
Finish like focaccia: brush with olive oil and sprinkle flaky salt; add garlic, rosemary, or both if you want the classic flavor cue.
Adjust the format: if using flat bread (naan/pita/tortilla), warm and then slice or fold to mimic focaccia’s scooping shape.
If your substitute is denser than focaccia, keep oven time shorter and rest briefly after warming so the crumb doesn’t dry out.
