I wouldn’t worry too much about the amino acid profile of every single snack. If you’re getting enough complete protein throughout the day and your overall diet is varied, that matters much more.
One of my favorite options is also fluffy oats with egg whites and chocolate. It’s filling, tastes great, and is a good way to satisfy a sweet craving while getting some extra protein in.

Greek yogurt with a scoop of protein and some frozen berries is probably my number one. Takes 2 minutes and actually feels like food instead of another shake.
Beef jerky is up there too when im out of the house. And if im being lazy at night cottage cheese with a little honey usually saves me from destroying a bag of sweets lol.
Cheese is dangerous for me because I can easily turn a “protein snack” into 800 calories without noticing --

I usually go for protein yogurts, but when I want something seriously good, I throw some frozen berries or a banana, protein powder, and a bit of milk into a blender. You end up with a massive bowl of thick protein ice cream -- Tons of protein, kills the sweet cravings, and you can destroy a whole bowl in front of the TV without feeling like you’ve completely ruined your diet. --

Triple zero Greek yogurt mixed with PB2 powder and dark chocolate whey isolate. Over 50 grams protein and tastes f-n delicious.

Date sugar/Honey glazed homemade jerky.
Commercial dehydrator makes about 5lbs at a time.
But on a budget hard boiled eggs. Endless seasoning options to keep em from getting boring.
Chicken thighs lately since beef went sky high. Buy them by the case and freeze em.
Organic green bananas as well decent protein and a bit less sugar while green.
Greek yogurt peanut butter protein shake with avocado banana and berries.

Greek yogurt + whey, cottage cheese, jerky, and tuna pouches are basically the top 4 across most forums and athlete snack lists. All are complete-protein, high-leucine options that support MPS between meals. --

I love me some cottage cheese scrambled eggs. 4 eggs, and 1/2 cup cottage cheese. Can be topped with hot sauce and salsa. Yum

I’m a hunter, so venison jerky and snack sticks.

I enjoy protein yogurt drinks or just protein yogurt in the cup but liquid makes it fast and easy. Ill pair that with a built puff bar then I feel soild and got 40gs of protein for like 300cals maximum. Also idk if your in the states but target always has crazy protein snacks ive been getting like rice crispy bars but with 20g protein or brownies with 20gs. I also enjoy a good beef stick.

When I’m in a legit deficit of close to 1000 calories a day, I’ll eat 2 scoops of chocolate casein protein with minimal water and made into a pudding. I salt it and wash it down with a Coke Zero and it tastes amazing and keeps me from waking up in the middle of the night starving.

My snack of choice is SHIN RAMYUN with 16 oz of fat free cottage cheese and three eggs. Top it off with Chili Garlic Sause and home-grown chives and Thai basil. makes me a happy man!

I love cheese but try to avoid too much cuz of the sat fats.

Dutch cheese like real gouda is amazing

I’m guilty of using core power elites and quest protein milkshake RTD’s to hit protein goals lol. Expensive habit. I’m lazy when I’m not training.
Idk if that counts

Whatever they are running at my job. I’ll pull a protien shake off of the line

"What everyone like to eat while chilling out on the sofa between main meals."

What is a "main meal"?
Bodybuilders , most especially on gear must have their diet totally on point. That usually means every meal is a main meal and there are no snacks.
I mean I had snacks as a child after recess, but then I grew up.
If you are unprepared, lack self control, or just in a total unforseen bind then you cant go wrong with Cheese, Milk, Greek Yogurt, unsalted nuts & seeds like pumpkin, or the old trusty can of tuna.
