I’ve been making this homemade version of a Jersey Mike’s Italian sub lately and I just wanted to share because it’s a relatively cheap meal that can feed a family of 6. And it tastes so close to the real thing! 
Sub rolls from Walmart: $2.48 for 6 rolls.
Italian seasoning: $1.00
Shredded cheddar: $2.00
I put a little butter on top of the bread rolls and sprinkle seasoning and cheese and bake for about 10-15 minutes at 350. Or until cheese is crispy. You can skip this and just toast plain bread if you want to save on cost a little bit!
Sliced pepperoni: $3.50
Sliced hard salami: $3.50
(I get the prepackaged stuff from Walmart)
Sliced cheese: $2.00
Iceberg lettuce: $1.28
1 onion finely sliced: .60
1 large tomato: $1.00
Red wine vinegar: $3.48
Canola oil: $3.00
Mayo: $4.00
(you can totally swap or remove ingredients to your liking to save on cost!)
Total: about $27 for 6 subs! You could even cut the sub rolls in half like I did in the photo to make more sandwiches, especially if you have little ones at home. We normally spend $13-$15 per sub when we eat out so this is a great alternative that we’ve been loving!
Edit since this is getting popular: I also add a little salt, pepper, and Italian seasoning to the sub after putting the oil, vinegar, and Mayo on!
