Combine the mayo, avocado, green chile, lime juice, cumin and salt in a blender. Blend until well combined.
Taste and adjust the seasonings. Set aside.
To make the bacon-wrapped sausages:
Preheat a cleaned grill to medium heat.
Cut the bacon slices in half crosswise. Cut each sausage crosswise into four equal pieces.
Lay one piece of bacon on your work surface. Place one piece of sausage at one end of the bacon and roll up, wrapping the bacon around the sausage. Repeat with the remaining pieces of bacon and sausage.
Thread the wrapped sausages onto skewers.
Grill the skewers, turning often and taking care not to let the bacon burn, until well browned all over, about 15 minutes.
Carefully remove the grilled sausages from the skewers and serve at once with the dipping sauce on the side.
