Cook boneless skinless breasts by boiling or broiling til done. Set aside to cool, then shred into bite sized chunks.
In the meantime, steam broccoli til done, but not mushy. Should be cut into bite sized pieces also.
In a large bowl or casserole dish, combine soup, mayo, curry and lemon juice. Stir in chicken and broccoli til blended together. Sprinkle top with cheddar cheese. Bake in the oven at 350 degrees until cheese is melted and bubbly. I usually serve with a side of white rice w/ butter. But you may choose any side.
