Good idea to bin the spam, it’s terribly poor quality meat but I ate it at your age too.
You can use the carcass with veg peelings to make stock for soups or stews. There’s loads of meat on the back you can use in soups, I’ve fried it up for fajitas.
I find sunflower oil less smelly when your frying.
If you buy plain flour that you’d usually use in batters etc you can make pitta breads, wraps and flat breads really cheaply and they freeze well.
If you wash, peel and chop the carrots they freeze well. Carrots can go soft quickly, doesn’t matter where you buy them it’s just what they do. I use tie handle bin bags
to freeze in a layer then I shake them and voila ready to use & I think freezing makes them cook quicker.
I buy chicken thighs too, much better flavour.
