Place sausage in a large, deep skillet. Cook over medium high heat until evenly brown. Drain and rinse in colander under cold water, breaking sausage into pea sized pieces.
Return to skillet along with the condensed milk, and heat over medium until just bubbling. Immediately stir in the cornmeal and pepper and reduce heat to simmer. Continue cooking, 5 minutes total; mush will be stiff.
Pack into 8x4 loaf pan, cover and chill overnight. To serve, cut into 1/4 to 1/2 inch slices and saute until golden in nonstick skillet.
