As a kid this was a favorite Sunday morning breakfast. On Saturday my dad loved to cook huge breakfasts. My mom cooked Monday through Friday...but on Sundays while Mom was putting on her makeup and heels and Dad was tying his tie we had an easy-to-prepare breakfast such as Avocado Toast. In the '60s avocados were still a little strange for most Americans and were not as easy to get. Lucky for us my Uncle George from Lakeside CA grew his own. We treated them like gold. For Avocado Toast we used only about 1/8 of the fruit. You can use 1/2 or even more per toast. A dense, hearty wheat bread works well but I like all kinds.
