Brown the sausages whole first. The sausage will remain so juicy if you brown it whole in the pan first. Don’t skip this step!
Cut the veggies into similar-sized chunks. To promote even cooking, make sure the veggies are sliced into evenly-sized pieces.
Add the bell peppers & onions in raw for extra texture. For added crunch, refrain from sautéing the bell peppers and onions like you do the mushrooms and potatoes.
