In large skillet, cook ground beef until partially cooked. Add vegetables; cook and stir until vegetables are tender: drain well. Add tomato paste, water, and paprika. Remove 1 cup of this mixture and reserve for Biscuits (below).
Add pork and beans and lima beans to beef mixture and bring to a simmer. Reduce heat and let simmer while preparing biscuits.
For biscuits, sift flours, baking powder, salt, and Italian seasoning into a medium mixing bowl. Cut in butter until particles are fine. Then add milk all at once, stirring, until dough forms. Knead dough on floured surface 6 times. Roll dough to a 12×9? rectangle. Spread reserved meat mixture over dough, and roll up, starting with 12? side of dough. Seal edge and cut into 1? slices.
Place meat mixture into 9×13? glass baking dish. Top hot mixture with biscuits. Bake at 425 degrees F for 25-35 minutes until casserole is bubbling and biscuits are golden brown.
If you don?t feel like making the biscuits from scratch, you can use canned refrigerated biscuit dough. Cut a small circle out of the center of each biscuit, place biscuits on hot beef mixture, spoon a bit of the beef mixture into the hole in each biscuit, and top with the cut-out circle of dough.
