Grilled Tuna Steaks with Avocado, Cucumber & Tomato Salad

To grill frozen tuna steaks, first marinate them for about 15 minutes in a mixture of olive oil, lime juice, coriander, salt, and black pepper. Preheat your grill to medium-high heat and grill the marinated steaks for approximately 3 minutes on each side. This will give you a perfectly cooked, juicy tuna steak.

If you don't have fresh lime, you can substitute it with lemon juice for a similar zesty flavor. For the coriander, parsley can be used as an alternative. If you're looking for a different salad base, consider using bell peppers or radishes instead of cucumber and tomatoes.

While you can prepare the salad ingredients ahead of time, it's best to assemble the salad just before serving to prevent the avocado from browning. If you need to prepare it in advance, store the diced avocado separately and add it to the salad right before serving.

This grilled tuna steak recipe is gluten-free and can be made dairy-free as well. It's also suitable for those following a low-carb or paleo diet, making it a versatile option for various dietary needs.

In addition to the refreshing avocado, cucumber, and tomato salad, consider serving grilled vegetables, quinoa, or a light rice pilaf as side dishes. A citrusy coleslaw or a simple green salad would also complement the flavors of the grilled tuna nicely.
