Sub in a Tub – the Perfect Meal Prep Recipe

This riff on Jersey Mike’s original sub in a tub takes amazing meats, veggies, cheeses and sauces and layers them into a meal prep container, so that you just need to grab and go on a busy morning.

They keep just fine for a few days in the fridge, but if you need to store them longer, package the sauces separately so that the veggies don’t sog out.

Honestly, I think it tastes even better the next day (or a few days later) because the flavors have had a chance to really develop.

No more soggy buns! With this Sub in a Tub lunch or dinner idea, you never have to worry about what to eat!

How to Make Sub in a Tub

  1. Get some meal prep containers. I use cute glass ones that I found at Costco, but any will do. These reusable meal prep containers are dishwasher safe and just fine.
  2. Layer in your ingredients, starting with the meats and end with the sauces.
  3. Package the sauces separately if you can’t eat it within a day or two.

Sub in a Tub Variations

  • Turn it into a Cobb Sub in a Tub with hard-boiled egg, blue cheese, and leftover rotisserie chicken (how to make a rotisserie chicken)
  • Go Southwestern with grilled chicken, black soy beans, and this Creamy Jalapeno Dip that is also an amazing dressing
  • Try an old-school deli favorite with sliced roast beef, a creamy horseradish, and lots of crunchy veggies
  • Enjoy a taste of the Mediterranean with a scoop of this Mediterranean Tuna Salad plus crunchy red bell peppers, cucumbers, and a few capers

Chef’s Tips

  • Use what you’ve got! Don’t worry about buying fancy ingredients for this dish – it can be as humble or as gourmet as you like.
  • The recipe below is pretty simple, but you can change up the cheeses (think about feta, blue cheese, sharp cheddar), switch up the meats, add different veggies (olives, baby kale or spinach, jicama), and add whatever sauces and dressings you like.
  • Add a pinch of your favorite Italian or Greek dried spices at the end, or a pinch of salt and a grind or two of pepper.
