Is this a healthy eating schedule/diet?

I'm a 19-year old college female. I'm 5'1'', and i'm 113 pounds. I've recently gotten into eating healthier, so i was just wondering if my eating habits are healthy.

so i wake up everday between 8 and 8:30 am. I drink some water, and then i have a serving of plain oatmeal with whatever fruit i might have.

I eat lunch around 12-1 pm, and the main thing i eat is salad which has: spinach, tomatoes, cucumbers, baby corn, jalapenos, a little feta, and about 1/4 cup of beans, usually black or chick peas, or if not beans, tofu. No dressing, ever. On the side, i usually eat fruit with 1/2 c of plain greek yogurt, wheat bread with honey and avacado, or something unhealthy like an egg roll or a cookie--depending on what my dining hall has that day.

dinner is usually the same exact thing as lunch, which i have around 5-6.

i usually never eat a snack in between meals since i don't get hungry. If i do get hungry, i snack on fruit.

around 8 or 9 pm, i'll make myself hot chocolate or a french vanilla cappucino (the powder is 25 calories per tbsp with 0g sugar) and eat a small piece of dark chocolate.

I guess i'm wondering if this is healthy because i kept track of my calories for a couple weeks on an iphone app, and my calorie intake averaged around 1100 a day. I know not eating enough puts your body into starvation mode and slows down metabolism, but if i'm not feeling hungry, is it doing that?
should I try to get more calories in? Should i focus that much on calories? Or should i just focus on WHAT i eat?

You are misinformed about starvation mode. You eat every day throughout the day, therefore your body is not starving. It takes 72 hours of fasting to get even close to starvation mode. You're fine.

But when it comes to calories, you are under. An extra 300 calories a day would suffice. If you split it up and ate an extra 100 calories at each of your 3 meals, you'd be fine. The worry is that you're not getting enough enough micro-nutrients on such a low calorie diet. The foods you're eating are great, but it's just not enough.

An easy way to add calories and healthy fat from your diet (since your diet is very low fat) would be to add olive oil, coconut oil, or avocado oil to your salad. You can make a creamy dressing with plain greek yogurt, lemon juice, and hebs.

A few almonds, extra feta on your salad, or even swapping out a glass a water for a glass a milk can help you get there without weighing you down.

You're a young woman, not a 92 year old woman. Eating like a bird isn't doing you any favours in the long run.
