My dietitian has asked me to aim for double the RDA of protein a day, so that's 100g. Here are a few things that are great protein providers:

Pea protein powder = 20g protein per serving
Whey protein powder = 43g protein per serving
Chia seeds = 4g protein per tbsp
Prunes = 1g protein per 30g (5 prunes)
Duck eggs = 13g protein per egg (soft boiled takes 6-7 minutes)
Peas = 4.6g protein per serving of 85g
Protein yogurt = Between 14g - 20g protein per pot
Banana = 1g protein
Avocado = 2g protein per 100g
Jersey/Channel Island Milk = 4g protein per 100ml
Smooth PB = 4.1g protein per 15g (tbsp)
Nutella = 3.9g protein per 40g

You can easily make a smoothie with 300ml Jersey milk (12g protein 225 kcal) whey protein powder (43g 240kcal), 2tbsp peanut butter (8.2g protein 188kcal) and 2 tbsp chia seeds (8g protein 139 kcal) which will give you a tasty and filling breakfast with 71.2 g protein and 792 calories.

I do find if I have something like that, then I'm not hungry until 3 or 4 in the afternoon, pr I've split it in half and had the 2nd half for lunch after blitzing it again with some ice to freshen it up. It's good for days when you're at the hospital, especially during lockdown as there's not much open.

Chia seeds, when soaked a liquid, go jelly like. So really easy to swallow and very nutritious.
