For the shrimp:
- Mix all ingredients with the shrimp in a large bowl and let marinate for at least 10 mins (even longer is better)
- Place shrimp on skewers and grill them on med-high heat for 2-3 mins per side, or until charred slightly. Remove from grill or grill-pan.*
For the corn:
- Shuck corn to expose kernels.
- Coat corn with olive oil and sprinkle with salt and pepper.
- Place corn in aluminum foil and roll up, pinching the ends.
- Grill on med-high heat for 30 mins (turning sides every 10 mins).
- Remove corn from grill and open aluminum foil.
- Let cool before cutting kernels off the cob.**
For the salad:
- Add shrimp and corn to a large bowl.
- Combine with tomatoes, bell pepper, onion, and avocado.
- Mix well and then squeeze the juice of 1 lime over salad.
- Add chilli powder, cumin and salt and pepper and cilantro, if using.
- Store in fridge for up to 1 week.
*Alternatively you could use pre-cooked shrimp and let thaw and then marinate in mixture for 30 minutes rather than grilling.
**Or use 1 1/2 cups of canned corn and bake in the oven at 400 degrees for 10 mins (watch carefully to make sure it does not burn).
