Some of my go-to frugal ingredients are:
- Tinned fish (sardines, tuna). So versatile; great for pasta dishes, salads or on toast with some tomato.
- Eggs: omlette with almost anything, boiled as a snack, or for a simple yet tasty carbonara.
- Frozen veggies - super cheap and handy to have in the freezer. I always keep frozen spinach, carrots, and peas; they're versatile and convenient.
- Rice - filling and inexpensive. It goes a long way, and left overs are delicious too!
Simple is best sometimes; a hearty vegetable soup or stew can be made for little cost and is warming and satisfying. Curry's are also a great cheap meal, full of flavour, and you can make them as mild or spicy as you like with some great frozen or tinned ingredients.
Lentils and beans are another affordable staple that bulk up meals; they're versatile too and packed with fibre and protein!
Who doesn't love a challenge that encourages creativity, especially in the kitchen!
