Follow these simple steps to create your delicious Avocado Tuna Salad Blend:

1. Prepare the Avocado: Cut the ripe avocado in half, remove the pit, and scoop the flesh into a mixing bowl.
2. Mash the Avocado: Use a fork to mash the avocado until creamy. It is okay to leave some small chunks for added texture.
3. Add the Tuna: Drain the tuna and add it to the bowl with the mashed avocado.
4. Mix in Other Ingredients: Add the Greek yogurt (or mayonnaise), Dijon mustard, and lemon juice to the bowl.
5. Season: Sprinkle in salt and pepper according to your taste preferences.
6. Incorporate Additional Ingredients: If you’re using optional ingredients like celery or onion, fold them in now.
7. Combine: Gently mix everything until well combined. Be careful not to over-mix; some chunks of avocado add to the dish.
8. Taste and Adjust: Taste the salad and adjust the seasoning if necessary.
9. Serve Immediately: Enjoy your Avocado Tuna Salad Blend fresh. Alternatively, you can store it in the refrigerator for later.

This effortless preparation makes the Avocado Tuna Salad Blend a go-to recipe for a quick breakfast.
