Did I eat enough calories?

I'm a 15 year old male & today I ate approx. 1300 calories, which consisted of; 

-1 Peri Peri Chicken burger from Red Rooster (314 cal)
-1 Large frieds (600 cal)
- 5 Arnotts Raspberry shortcakes (69 cal each)
- 4 strawberries (4 cal each) 
I know what I ate wasn't the healthiest, but based on the calories that I consumed, did I eat enough?
I was pretty much sedentary all day, except I did 20 minutes of HIIT cardio.

*Yes, ive lost a lot of weight over the past 6 months or so, as I was quite overweight. i'm not too sure of my weight, however I'm at a bf% of about 10-15 maybe. 

Even if you are trying to lose weight, that's at least 500 calories short, and probably closer to 800 calories too little.

An overweight, sedentary teen male should eat AT LEAST 1800 calories for weight loss; an overweight, active teen male should eat at least 2100 calories for weight loss. If you did 20 mins of HIIT cardio, that qualifies you as active

I don't see any other post from you, so I can't tell if you are overweight, or not.  Regardless, a teen male should almost never be eating less than 1800 calories.

One big problem dude, even if you were eating enough calories your for sure as hell not eating enough nutrients, those foods are poooooooooooor. Anyway to know your caloric intake theres a couple things ya gotta figure out. Are you trying to lose weight or put on muscle? OR maybe your trying to just maintain your current weight, in any case your a growing lad so I wouldnt recomend anything other then a good clean healthy bulk to be honest, either way 1300 is too little, on a cut never go below 1500 and it should only be that low when your near the end of your cut and below 10% bodyfat, without knowing your height or weight I can't really give you a good figure but guideline is about 2000 calories a day with a good selection of healthy wholesome foods like grain breads/lean meats (THE USUAL). Like I say without knowing your goals or your current state I can't be of much further help to you, good luck.
