Grilled Shrimp with Avocado Salsa

I am a serious seafood lover. So when I found this recipe at Woman Know Thyself's Facebook page, I had to borrow it. 

Ingredients:

For the Shrimp:
24, 16-20 count prawns, peeled and deveined
18 cherry tomatoes
2 tablespoons fresh thyme
3 tablespoons shallots, minced
1 tablespoon cumin
2 tablespoons basil, chopped
¼ cup extra-virgin olive oil
Kosher or sea salt and cracked black pepper to taste
½ lemon (use while grilling)
6 skewers (soak the skewers in water for 6 hours before using)

For the salsa:
1 ripe avocado, diced
1 small red onion, diced
1 small roma tomato, seeded and diced
2 tablespoons cilantro, chopped
½ lemon, juiced
2 tablespoons olive oil
1 tablespoon white vinegar
Kosher or sea salt and cracked black pepper to taste

Directions:

For the Shrimp:
Marinate the shrimp in all the ingredients, except the cherry tomatoes and lemon, for at least 4 hours before grilling. Skewer the prawns with the tomatoes and grill, 3-4 minutes each side. Season with the lemon juice, salt and pepper while grilling.

For the Salsa:
Mix all the ingredients lightly and let set in the refrigerator for 15 minutes.
