Place the bread straight onto the rack of a pre-heated oven at 160C / 140C Fan, and cook for 7-9 minutes. Allow to cool and then break into pieces.
Prepare the tomatoes, cucumber, radish, pepper, lettuce, and red onion, chopping them all to preferred size for the salad.
To make the dressing add the olive oil, sumac, lemon juice, shallot and Mrs Bridges Lemon & Lime Marmalade to a mason jar. Season with salt and pepper, and then close and shake to emulsify the dressing. Adjust the seasoning and add more sumac if desired.
Assemble the salad with the freshly chopped vegetables, coriander, mint, flat-leaf parsley and broken bread pieces.
Mix to combine before drizzling the dressing over the top. Serve immediately.
