Avocado Dressing for BLT Salad

Slice avocado lengthwise. Remove and discard pit and peel, and place flesh in the bowl of a food processor. Add basil, garlic, lime juice, and vinegar; process until combined. Slowly add olive oil through the machine's feed tube, and process until the dressing is smooth. It should have a thick but pourable consistency; give an extra squeeze or two on the limes to adjust consistency. Season with salt and pepper, and use immediately.
