Vegans can get 100g of protein in a day by eating foods that are high in protein, such as: 

Nuts and seeds: These can provide a lot of protein.

Dark leafy green vegetables: These include kale and spinach.

Tofu: This is a great source of protein and can be cooked in many ways.

Tempeh: This is another great source of protein.

Red lentil pasta: This can be made from protein-rich red lentil flour and can be used in a vegan bolognese.

Spirulina: This blue-green algae contains between 55 and 70% protein.

Other sources of protein include: 

Protein granola

Plant-based protein powder

Seitan

Many vegetarian protein sources are incomplete proteins, with the exception of dairy, eggs, soy, and quinoa. 

You can also try these protein powders and bars.
