1 (4 ounce) can sliced, crushed pineapple in syrup
1 tablespoon lemon juice
3 cloves garlic, minced
2 teaspoons salt
1 cup white sugar
6 boneless skinless chicken breast halves
In a medium bowl, mix pineapple and lemon juice. Set aside.
In a medium saucepan, over medium heat, combine garlic, salt, sugar and lemon juice. Bring to a boil, then cover and simmer until sugar is melted and quite a bit of juice remains, about 15 minutes. Remove from heat.
Pour lemon juice into a large saucepan. Add chicken breasts and set aside. Pour over pineapple/lemon mixture, stirring, until melted. Pour about 1/2 cup mixture over chicken and stir to coat. Cover and refrigerate chicken.
