    Are you an avocado lover? I will be the first to admit it took me a long time to give them a try, but once I did I was hooked. The best part is they are super good for you too. From healthy fats and fibre to anti-inflammatory and antioxidants, these little gems are a powerhouse.

    There are so many ways to enjoy eating avocados. Guacamole appetizers are a hit at parties. Want to impress your dinner guests? Give grilled avocados a try. Presentation perfect, and they can be served as an appetizer or side dish.

    If you are like me, I can just eat avocados with a spoon, a great lunch any day of the week. You can even make healthy chocolate pudding with them too.

    Suggestions / Recipe Tips

    • Canned tuna can be solid or flaked, packed in water or oil. You can also use flavoured tuna if you don’t want to add additional seasoning.
    • Buns or bread of any kind will work. You can also toast the bread if you like.
    • Salsa of any type is perfect. Hot, mild, medium and also salsa verde is a great option.
    • Lettuce can be replaced with baby kale, pea shoots, arugula or any other greens you like.
    • Tex-Mex seasoning can be swapped for taco seasoning or your choice of any combination of spices you like.
    • Fresh avocado works best, but in a pinch this sandwich can be made using guacamole in place of avocado. You will have to adjust the amount so the sandwich filling will not be too runny.
    • Serve immediately since this sandwich will get soggy quickly.
