Start by gathering all your ingredients. Make sure you have fresh soy and olive oils, along with the hot pepper juice, oregano, and garlic.
In a large mixing bowl, pour in the 4 cups of soybean oil along with the 1 cup of olive oil. Whisk together until well combined and smooth.
Next, add in the 1 1/2 cups of juice from your jar of hot peppers. This will add the essential flavor and tang to your sauce.
Sprinkle in the 1 teaspoon of oregano and the 1 teaspoon of minced garlic. Whisk again until all ingredients are fully incorporated.
Give your sauce a taste. If you prefer a spicier kick, you can add more hot pepper juice or a pinch of cayenne pepper.
Transfer your Copycat Mr. Submarine Secret Sauce into a glass jar or bottle. Seal tightly and refrigerate. Let it sit for at least an hour before using to allow the flavors to meld beautifully.
