if you've only got one burner u can still do pasta or rice dishes with a tomato sauce. cook pasta or rice first then add to sauce u make. onion garlic tin of tomatoes plus any veg u want for sauce. add ur canned chicken or cut up bits of hotdog for a cheap non-refrigerated meat. alternatively instead of pasta use lentils, beans or small pieces of potato in ur sauce plus veg (courgette bell pepper kind of veg) to make it a one dish. if u have spices (e.g chili powder, paprika or cumin coriander for indian feel) this adds variety to the different base sauce u make. add the spices 3-5 mins after vegetables for 2 mins then add tin tomato n cook for 15-20 mins n ur done. doesnt use up too much gas as u cook on low. the sauce should reduce and the lentils or potato cooked enuff. dont forget ur salt n pepper. hope this is an ok suggestion n u like it. pls let me know.
