Seven ingredients and thirty minutes, and only the chicken is cooked.

This is not a pressed sandwich. The rolls stay as they came from the bakery.

Why This Recipe Works

  • Grilling cutlets whole and slicing after keeps them juicy.
  • A coarse pesto stays a visible layer rather than soaking into the crumb.
  • Fresh mozzarella is mild enough to sit under a strong pesto.
  • Crusty bread holds sliced tomato without going soft.
  • Leaving the roll untoasted keeps the sandwich soft against a crisp crust.

Ingredient Notes

Fresh mozzarella
Eight ounces, sliced. A defining component the title never names, and fresh rather than low-moisture.
Fresh tomato
Two medium ones, sliced. The other unnamed defining component.
Coarse basil pesto
Half a cup, spread thickly. Coarse rather than smooth — it stays a visible green layer in the cut face.
Crusty white bakery rolls
Four, split and left untoasted. The crust is what stops sliced tomato softening the bread.

How to Make It

  1. Chicken grilled marked and to 165°F

    Brush chicken with olive oil, season with salt, and grill or griddle until marked and 165°F.

  2. Rested, then sliced

    Rest the chicken and slice it.

  3. Rolls split — not toasted, not pressed

    Split the bakery rolls without toasting or pressing them.

  4. A thick layer of pesto

    Spread a thick layer of pesto on the rolls.

  5. Chicken, mozzarella, tomato

    Layer with grilled chicken, fresh mozzarella, and tomato.

  6. Closed — no leaves, no onion, no extra sauce

    Close and serve; add no leaves, onion, or extra sauce.

Four Layers in an Untoasted Roll

Nothing in this sandwich is cooked except the chicken - the pesto is a SPREAD rather than a sauce, and the roll is never put back on any heat.

  1. Closed, and three things refused

    Step 6 is an exclusion: NO LEAVES, NO ONION, NO EXTRA SAUCE. Rocket in particular is the obvious addition to a sandwich like this, and it is left out. What is in the roll is chicken, pesto, mozzarella and tomato, and nothing more.

  2. Fresh mozzarella, then tomato

    8 oz of FRESH mozzarella and 2 medium TOMATOES, both sliced. Both are DEFINING components the title names neither of. Fresh mozzarella rather than low-moisture is a deliberate pairing - it is mild and milky enough to sit under half a cup of strong basil pesto without disappearing.

  3. The chicken - grilled whole, RESTED, then sliced

    1 lb of cutlets brushed with 1 tbsp olive oil and 3/4 tsp salt, grilled UNTIL MARKED AND 165F, then RESTED AND SLICED. Whole first and sliced after: less cut surface in the pan means less moisture lost, and the rest lets the juices settle rather than running into the pesto. The char marks are what the grill is for - a pan would cook it but not mark it.

  4. A THICK layer of coarse pesto

    1/2 cup, spread thickly. Coarse rather than smooth matters visually and structurally - a coarse pesto sits ON the crumb as a distinct GREEN LAYER, where a loose smooth one soaks in and disappears. It is also the only sauce in the sandwich, which is why it goes on generously.

  5. The roll - split, and deliberately left alone

    4 crusty white bakery rolls, SPLIT WITHOUT TOASTING OR PRESSING THEM. That is the decision that separates this from a griddled sandwich. The crust is doing the work a toast would otherwise do: it holds sliced tomato and fresh mozzarella without going soft, so no heat is needed to firm it up.

Success Tips

  • Rest the chicken before slicing so the juices stay in the meat.
  • Spread the pesto thickly enough to read as a layer rather than a smear.
  • Leave the rolls alone — no toasting and no pressing.

Serving Ideas

Four sandwiches on a board, crusty rolls holding the sliced grilled chicken over a thick green pesto layer with fresh mozzarella and tomato. Nothing else.

Frequently Asked Questions

Should I press or toast the rolls?

No. The rolls are split and left as they are — this is an assembled sandwich rather than a griddled one.

Fresh mozzarella or low-moisture?

Fresh, sliced. It is mild against a strong coarse pesto, and it is what the cut face shows.

Can I add rocket or onion?

No — step 6 rules out leaves, onion and any additional sauce.
