Stuff You Need

When you get a Coronis sub it’s either: Ham or Salami.

Everyone knows the Salami are the best; If you prefer ham, just swap it.

  • They’re using cheap Cotto Salami – the hard-er stuff like Genoa is OK-ish
  • 1 green pepper, thin cut long-ways
  • 1 whole Cucumber, peeled and cut into 1/2″ pieces
  • 1 Tomato, sliced
  • Shredded lettuce is optional
  • EVOO or any neutral oil + herbs
  • Mayo (this is a New England sandwich shop, use Hellman’s)
  • 2-4 Homemade Bread Rolls (homemade recipe provided)
  • Salt + Pepper

The Bread Rolls and Why They’re Hard to Find

This is one of the main reasons people love these sandwiches but most of the bread rolls at your grocery store suck.

My Homemade Sub Rolls

These rolls are likely supplied by a Sysco truck (says my Dad), meaning regular folks can’t order them.

The best way to describe them is:

  • Fluffy
  • Airy
  • Slight crumb

Basically a bread built for lots of oil, mayo, water from veggies, and meat – this is why these sandwiches taste great the day of and why the next day they’re totally soggy.

Prep the Veg and Oil

Peel and slice cucumbers into 1/2″ rounds.

Thinly slice a green bell pepper into strips.

Take both of these and add a mixing bowl.

Their prepared sandwiches usually have tomato – I always remove it.

If you’re a tomato person, slice those too.

Set these to the side, not in the bowl.

The oil in their sandwiches is likely a cheap oil like canola or vegetable that’s mixed with something like oregano or similar Italian seasonings.

This is OK but I prefer a version of my oil with less vinegar for this sandwich.

In a bowl combine:

  • 1/3 cup EVOO
  • 1 tbsp Red wine Vinegar
  • 1/4 teaspoon salt
  • 1/2 teaspoon sugar
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon Italian seasoning
  • 1/4 teaspoon mustard powder
  • 1/4 teaspoon black pepper

Mix this well – ideally allow to sit for a couple of hours for the spices to re-hydrate and then add to the mixing bowl with the veggies; Allow that to soak and mix for ~15 minutes.

Make the Sandwich

Cut your bread roll from the side without going all the way through.

Lather on a generous amount of Hellman’s mayo on both sides, ~2-3 tbsp worth.

SALT + PEPPER the mayo – use ~1/4 tsp-ish or a few pinches – this salt flavor is absolutely there in these sandwiches.

Coronis’ subs take the Cotto Salami and cut it in half, and then put them across the sandwich. They aren’t known for lots of meat, but you can add as much as you like.

Then add your cucumbers, peppers, tomato, and lettuce.

Wrap up in parchment paper and slice in half.
