A Deli-style sandwich with vinegar-free mayo

Oh. My. Goodness. For over 8 years I have not been able to have store bought mayonnaise, but instead have had to make my own. It's always been enough, yet, never quite right, until....I made this sandwich. Let me tell you, this was the Deli-style sandwich I remembered from before my diet change. It was a perfect mayonnaise! They perfect everything! GF toasted bread, fresh lettuce and tomato from the Farmer's Market, and my homemade mayonnaise. Best sandwich EVER!

Here's the vinegar-free mayonnaise recipe: *Note that the results seem to vary, depending on the weather.

1 egg
1/2 Tablespoon of Lemon Juice
3/4 Cup Olive Oil (although, I usually end up using less)

1. Place the egg and Lemon Juice in a bowl and give a quick whirl with an immersion blender. You can also   use a min food processor. 

2. Add the Olive Oil and blend until it thickens and becomes Mayonnaise-like. When using the immersion blender it can happen fairly quickly, while the mini food processor can take a while longer.

Store in fridge in a container with a tight fitting lid.
Use in 3-4 days.
