Precook lima beans according to package directions, until almost done, then add remaining frozen veggies and cook 2 minutes longer. Drain.
While the beans are cooking, saute the onions in butter, until almost clear, add garlic and saute a bit longer. Mix in flour and spices and stir vigorously until all flour is mixed inches.
While still stirring vigorously slowly add half and half and broth. Bring the mixture to a boil, stirring occasionally.
While the broth is cooking begin rolling out the biscuits until they are thin circles approx 7 inches in diameter. When the mixture starts to boil add the veggies and mushrooms, stirring until they've all been coated.
Place the rolled out biscuits in a muffin tin letting the edges hang over. Put a generous scoop of veggie mixture in the center of the biscuit. Then either fold over the overhang or bring the edges up and pinch together in the center to make a flower. .
