Unroll dough, and separate into 4 rectangles. Press seams together to seal. Cut each rectangle into 4 long strips about 1x6 inches.
Lightly roll each strip to form a rope, and twist each piece into a knot. Place on ungreased cookie sheet. In small cup, mix water and baking soda, stirring until dissolved.
Brush each dough knot with water mixture; sprinkle with coarse salt. Discard remaining water mixture. Bake 10 to 12 minutes or until golden brown.
Meanwhile, in 8-inch skillet, heat oil over medium heat. Add onion and cook 4 minutes, stirring occasionally. Add bratwurst; cook 4 to 5 minutes or until heated through. Carefully stir in cream cheese, Cheddar cheese and beer; pan will be full.
Cook 2 to 3 minutes, stirring constantly, until cheeses are completely melted. Remove from heat; top with green onions, and serve with pretzel bites.
