You're wearing mittens? Do you mean Oven Gloves?
At any rate, the way you phrase this makes me think that maybe you should just make a sandwich and leave the cooking to when your parents can watch you. You seriously sound like you're asking permission, which means you're scared to go it alone - which is an instinct you should listen to.
I'm not saying that to be mean, but 'a bunch of times' doesn't mean that you know what you're doing - and if you spill something hot that's too heavy for you to lift, you're all alone and there will be no one to call 911.
Go raid your fridge for things that are easy to make or can be microwaved (for right now) and talk to your parents about learning to cook some simple meals that they can help you practice.
Be safe.
