Trying to lose weight but struggling to find foods I can have

Before anyone suggests keto, I’m not interested in that and I don’t want to even consider trying it.

Okay so I don’t like most healthy foods and I don’t really know how to cook them. I am a fan of green beans and broccoli but how do I make green beans? Like the long ones? I want to try baking them but I don’t know if that’s a good way. I like carbs like potatoes and pastas. I don’t know how to eat food without carbs being one part. Like a chicken sandwich. I can make healthy chicken but then I want to add a slice of cheese, a sauce, and put it on bread. How do I avoid this? How do I make food without utilizing a carb? I want normal meals. I’m sorry. This isn’t really a question I guess. Just venting lol. I don’t know what I’m doing. I’m just wanting to lose about 50 pounds. I feel so fat and gross all the time.

I know I have to change my diet! That’s what I’m trying to do. I just don’t know how to cook that
