Place all ingredients for the salmon in a large shallow bowl and mix gently to evenly coat the salmon with the spices. Marinate in the fridge for 15 minutes.
Heat a grill pan on medium-high. Brush with some olive oil. Place the salmon fillets on the hot grill pan and cook for approximately 4-5 minutes. Using tongs, carefully turn over the fillets and cook the other side for 4-5 minutes until browned and just cooked down the middle. Remove from heat and set aside.
To Prepare The Rice
Heat oil in a large frying pan or wok on medium. Add garlic, onion and chilli. Sauté for a few minutes until the onion starts to caramelise.
Add the cooked rice, oregano, lime zest, lime juice and salt. Mix well and cook for a few minutes until heated through. Remove from heat and stir in the coriander.
To Prepare The Caramelised Pineapple
Heat a grill pan on high. Place pineapple slices on the hot pan and brush with melted butter. Cook each side for 3-4 minutes, basting with melted butter until starting to char and turn golden. Remove from heat and set aside.
To Assemble The Burrito Bowls
Place cooked black beans, paprika, lime juice, salt and pepper in a small bowl. Mix well. Shuck the corn cobs.
Grill the corn on an open fire for a couple of minutes until it starts charring. Alternatively, place on a barbecue or oven grill and cook until starting to brown. Remove from heat and cool slightly. Using a sharp knife or corn stripper, remove the kernels into a bowl and set aside.
Take 4 shallow rimmed bowls (approximately 20cm). Place 2 lettuce leaves in each bowl. Place a pineapple slice over the lettuce in each bowl. Divide the rice equally between the bowls. Add black beans and charred corn. Place a salmon fillet over the bed of rice, corn and beans. Top with green pepper, avocado, salsa and hot chilli sauce. Garnish with lime wedges and micro herbs.
