Mix the bacon, hominy, corn, onion, tomatoes and parsley together in a large bowl.
In a saute pan, bring the olive oil, garlic and rosemary sprig to a sizzle. Set aside for 20 minutes. Discard the rosemary twig, reserve the oil and put the garlic cloves in a food processor along with the cheese, salt, pepper, lemon zest and lemon juice. Process until smooth, then add to reserved oil. Mix the dressing into the salad.
