Tuna Ceviche

From the magazine Traditional Home April 2007. 

 12 oz fresh tuna fillet 

1/2 cup lemon juice 

1 ripe avocado, chopped 

1/3 cup finely chopped red onion 

1 serrano pepper, seeded and chopped 

2 Tbs orange juice 

2 tbs soy sauce salt and pepper 

 Cut tuna into 1/4 inch cubes after removing any white pieces that might make it tough. Place in large bowl. Add lemon juice. Stir to coat. Let marinate 5 minutes. Drain tuna and discard lemon juice. In another bowl, combine avocado, onion, serrano pepper, orange juice, and soy sauce. Fold in tuna. Season to taste with salt and pepper. Fabulous.
