Preheat the oven to 220C, fan-forced. Line an oven tray with baking paper. Thinly slice the zucchini lengthwise (see Kitchen hack). Cut the tomato into 1cm-thick wedges.
Step 2 — Bake veggies
Put the zucchini and tomato in a bowl. Add ½ tsp dried oregano and 2 tsp olive oil, season with salt and pepper and toss to combine. Put on one side of the lined tray and bake for 12 mins.
Step 3 — Warm rolls
Cut a slit lengthwise down the middle of the rolls. Add to the other side of the tray with the veggies and bake for a further 8-10 mins until the veggies are tender and the rolls are warmed through and crusty.
Step 4 — Dress feta and leaves
Put ½ tsp oregano*, 1½ tbs olive oil and 1 tsp honey in a large bowl. Season with salt and pepper and whisk to combine. Add the salad leaves, crumble over the feta and toss to combine.
Step 5 — Serve up
Spread the rolls with the red pesto, then fill with the baked veggies and salad. Toss any remaining veggies and remaining salad together and serve with the subs. Enjoy!
Step 6 — Kitchen hack
Use a mandoline or vegetable peeler for super-thin zucchini slices.
