Use medium pot. On medium heat add olive oil to heat; brown meat while breaking up sausage, add onions. When about half way done add mushrooms and saute until soft. Stir in risotto.
Add one ladle full of broth. Stir. Add herbs if using. Reduce heat to simmer. As risotto absorbs broth continue adding one ladle full at a time while stirring. This should take about 35-45 minutes. When a creamy consistency is reached and risotto is cooked (taste), remove from heat. Stir in cheese.
