In a large pot, heat margarine & saute the asparagus, peas, carrots, cauliflower & kohlrabi for 5 minutes stirring to ensure all are coated. Add a little water, salt & pepper. Simmer till the vegetables are tender but still chewy. In a small bowl, mix the cornstarch with 2 tb water & add to vegetables stirring till sauce has thickened. Serve with parsley.
