Ingredients You Need

- Small flour tortillas – You can use fajita size tortillas or street-taco tortillas. The ones I use are about 4″.
- Cooked corned beef – This recipe assumes you already have cooked corned beef. You can also start by making your own. It’s quite easy with this recipe.
- Avocado slices – Depending on the size of your avocado, you’ll need about 1/2 of an avocado.
- Shredded cabbage – I like to shred both purple and green cabbage for the color. You can also use a coleslaw mix.
- Diced red onion – Adds a little spiciness to the tacos. If you don’t like red onions, you can omit or use yellow onions.
- Cilantro – Fresh cilantro adds a bit of the Mexican fusion to these tacos.
- Thousand Island dressing – You can make your own (recipe below) or use store-bought dressing.
Helpful Tips
- Warming the tortillas makes them more pliable and enhances their flavor. A hot, dry skillet works best, but wrapping them in a damp cloth and microwaving for a few seconds is a quick alternative.
- While it’s tempting to load up each taco, a balanced ratio of corned beef to toppings ensures every bite is perfect.
- Feel free to mix a bit of hot sauce into your Thousand Island dressing for an extra kick.
