Your saucepan is fine. You can substitute any sort of pasta in recipes. Penne or fusilli are often cheapest and as they are in small pieces will work fine in smaller pan. Two big handfuls is a portion but do extra, it’s cheap and less annoying than running out of cooked pasta mid meal!
I second the cream cheese recipe above, that’s a regular standby for us!!
vegetarian recipes have an easier learning curve as you don’t have the germs from raw meat to worry about.
fajitas- brilliant. Get all your sides ready (the grated cheese, yoghurt if u r having it). Open packet and put one on plate ready to microwave.
chop the onion - look up a YouTube video on how!!
chop peppers and any other veg.
chop garlic if using.
get the oil hot. Use maybe a tablespoon (about 3 ordinary spoons?). Drop one piece of onion in and if it sizzles, it is ready.
add all the onion. Turn the heat low. Give this a few minutes - five or so - but stay with it turning the pieces regularly and moving them about. After the onions have had a couple of minutes head start add the rest of the veg. You’ll see the onions go a bit more translucent, then softer, then some will get a bit golden or crispy. Take one or two out to try.
the great thing about cooking yourself is you get everything just the way you want it. Once you’ve made a recipe a few times you’ll know whether you prefer crispier onions for example and you’ll do them for a shorter or longer time.
just taste things every couple of mins after the first 4, keep the heat on the low to medium side. After maybe 8 mins should all be cooked but it’s fine to give longer.
the tortilla - 80p for 6 from any supermarket - needs only about 10 seconds in the microwave. Take it out, add some veg, toppings, enjoy. You’ll have about 2-3 tortillas worth probably.
id recommend avoid meat for first while as you can get sick eating undercooked meat so won’t be able to taste as you go along. I think learn basics with straightforward veg and eggs first.
enjoy!!
