Don’t overlook the usefulness of a pressure cooker onboard. Pressure cookers come in an assortment of sizes. I have a 4, 6 & 8 quart cooker. You only need a cooktop. Electric or gas. Cooks fast. Pot roast, potatos, carrots, green beans and onions cooked from start to finish and on the table in 35 minutes.
This is an excellent way to cook any vegetables, without boiling them to death.
