Would pasta salad be too much?

This morning, I ate a tiny bit of peppers and onions and nearly a whole basket full of chips and dip, which I'm not proud of. Then my family and I went to a Chinese restaurant, and I ate some chow mein, rice, bred, an egg roll, cantaloupe, and four ounces of ice cream. Is it okay if I eat some pasta salad now, or have I had too much already today? I'm about 5'6, and weigh around 120lbs.
