Avocado and Chicken Sandwich?

I want to make an Avocado and Chicken sandwich but I’ve never done it before.

What ingredients can I put in it to make it really good?

I have some Artisan bread, chicken breasts and two ripe avocados.

The best and easiest recipe will get 10 points.

Good Luck and Thank you.
Thanks for the ideas so far. I’m going to the supermarket to put some tomatos, lettuce and bacon in the sandwich. (This are ingredients I keep finding on the internet.)

Which tastes better; mayo or cream cheese? The only time I’ve ever mixed avocado and cream cheese is in sushi and I don’t know if cream cheese and chicken will taste good? What do you think?

BTW, this dinner is for my brother. He doesn’t like onions or red peppers or spicy food.
