Step 1In the bowl of a blender, combine the lime juice, vinegar, garlic, cilantro, green onion, salt, cayenne pepper and avocado and blend. With the blender running, slowly add the oils to form a thick, creamy dressing. Taste and adjust the flavorings, and seasoning if desired. This makes a scant 2 cups avocado dressing, which will keep, covered and refrigerated, up to 3 days.
Step 1In a large bowl, combine the romaine, chicken, one-half each of the crumbled feta and pumpkin seeds, the tomatoes, onions and diced avocado. Add one-third cup dressing and toss gently to combine. Taste the salad, adding additional dressing as desired and seasoning to taste with salt and pepper. Divide the salad among 4 plates, topping each with the remaining cheese and pumpkin seeds. Serve immediately.
