I have many recipes which I cook in a single vessel, usually a slow cooker, which are energy efficient but the ingredients probably mean they are not frugal. One meal we often make because it is delicious, quick, easy is also frugal though that's never been a thought before:
Pasta with salmon (or virtually anything!!) :
Ingredients
- spaghetti 60g of dry pasta per serving (any pasta will do but spaghetti works best)
- salmon filet 40g per serving (that's half a pre-packed supermarket filet)
- soft cheese with garlic and herbs couple of tablespoons or to taste
- parsley (optional as it adds 75p cost for a potful)
- parmesan
- black pepper
Method
- cook the pasta as usual but stop just before it's ready, just al dente, as it will continue cooking
- skin the salmon and dice into 0.5cm cubes, important and definitely not more than 1cm
- drain the pasta leaving perhaps a cup of water in the pan
- add the soft cheese and mix thoroughly to coat the pasta (a carving fork works well)
- add the diced salmon and over a very low heat mix (carving fork) till the salmon is cooked
- scatter with parsley
- dress with black pepper and grated parmesan
- serve with green salad if desired
The beauty of the above is it is very adaptable; leave out the salmon or substitute with a vegetable such as broccoli, cauliflower, courgette, green beans, cherry tomatoes, loads of possibilities. If using a "hard" vegetable (e.g broccoli) break into larger pieces and blanch to crisp before adding to the pasta.
The Roasting Tin by Rukmini Iyer is a brilliant recipe book for +/- £10 with 74 "one dish dinners." There are four editions. Some are frugal but I haven't used it specifically for this. There are four versions including meat and vegetarian/vegan. I was given it for Christmas and have yet to have a failure. Great for tea, supper with friends or some for an informal dinner party. On a walking week each couple was responsible for an evening meal for ten. I chose two recipes from the book, huge success as each couple asked me for the recipes and not just out of politeness. I was very nervous and then very happy!!!
