Seared Tuna, Herb Salsa & Avocado

Ahi tuna is a very lean fish, so is a popular addition to an aggressive fat loss diet.  However, this recipe adds some decadent avocado to provide some extra energy. It is nutrient-dense, versatile and will be perfect for keto or blood sugar management.   

The tuna will give you heaps of omega 3, B3, B12, vitamin A and selenium while the avocado and greens boost the vitamin B5, folate, vitamin C, vitamin K, iron, copper and potassium.  The herb salsa rounds out the flavour profile to make your taste buds sing.
