Any meal suggestions?

Since you say you're under your goal, I'm guessing you mean you don't want to simply eat more food at meals or between meals, so my suggestions are based on this assumption:

You can look for more calorie dense foods. For example, if you are having fruit, you could look for more caloric fruit than what you've been eating. Then you're eating the same amount, but will take in a bit more calories.

Are you making sure to cook your meat & veggies in a healthy oil? That will add calories without seeming like more food. Plus, it will help fill you up.

Avocado is yummy and healthy and adds calories. I like it with smoked salmon but you can add it to sandwiches, toast, lots of things.

If you've been eating "diet" versions of processed foods (ex: fat free cream cheese instead of regular, or sugar substitute yoghurt instead of yoghurt with honey) then consider not doing that. The small bumps in calories will help you meet your goal, and you'll probably feel more satisfied anyway.

You can add a treat. I like to make my own hot cocoa, using cocoa powder, some foamed milk (but you don't have to foam it), a bit of boiled water, and like a tsp of whatever you like to sweeten stuff with. Cinnamon is good too, or a bit of peppermint. (Put the powder, then enough boiled water to get all the powder wet and liquidy, sweetener, fill up with milk. Use more like 50%+ water if you're using cold milk.)

If what you want is recipe ideas because you aren't great at making your own meals, I'd suggest doing a lot of research into meal plans, mixing and matching, substituting, trying stuff out. Don't do anything that strikes you as wrong for you, so be flexible. But as a basic guideline, your portion of meat + veg, 1 tbl oil of choice, herbs and spices, frying pan + fruit on the side. (Or if you were vegetarian/vegan, your protein option instead of "meat" -- mushrooms, tofu, etc.)

For lunch I always go for a salad. And it's pretty filling. My ingredients are 2 cups of baby lettuce, a whole small tomato, one grilled chicken tenderloin, and just a half oz of cheese... Plus I add flax seed to my salad because I need my fiber.

For dinner I usually do a chicken wrap. A multi-grain wrap with 1 cup of baby lettuce, 1/4 cup of low fat cottage cheese and a chicken tenderloin. Then a piece of fruit. It fills me up, and each meal is like 200 calories maybe more. I just do healthy snakes between breakfast and lunch, and then again between lunch and dinner. Most of the time is a smoothie. You can do a cup of milk and a banana or 2 cups of mixed berries, 1/2 Greek yogurt and a tsp of honey. It fills me up and quenches my thirsty throughout the day, expecially after a good workout..

Peanut butter, or its more amazing counterpart chocolate peanut butter
