Blueberry Dumpcake

My most sincere apologies for no picture. Perhaps I will update with a picture the next time I make this amazingness.

Blueberry Dumpcake
1, 20 oz, can crushed pineapple, juice reserved
3 c. blueberries, frozen or fresh
1/4 c. sugar
1 box yellow cake mix, dry
1/2 c. butter, melted
1/8 c. sugar
chopped pecans if desired

Preheat oven to 350 degrees. Drain the pineapple juice and combine with the melted butter. Spread the pineapple on the bottom of a 9x13 pan. Layer the berries next, followed by sugar (amount can be adjusted), the dry cake mix, the butter/pineapple juice mix, a sprinkling of sugar and chopped pecans if you wish. Bake for 30-45 minutes until golden brown and bubbly. Serve with or without ice cream. Don't be alarmed if the entire dish is consumed within an hour.
