Get yourself a decent stove. You can get them with oven and 2 hobs. We use ours all the time. Cooked pasta, stew, fish. The last meal I cooked on it was sausage mash and veg for 5 people. Omelette for breakfast or even knock up a load of porridge. Army rations are handy but any food that can be sealed in a bag and have a 10 year shelf life ain’t for me anymore!!
