What is one item vegetarians can eat to get their protein

The easiest (and possibly tastiest) answer is nuts.  All varieties of nuts: almonds, peanuts, cashews, pecans, hazelnuts – you name it.  And for those of you who like it smooth, peanut butter is an excellent source of protein with 4 grams per tablespoon.  Watch the salt though: the USDA recommends choosing unsalted nuts to keep the sodium intake low.

Rice and beans because they both have proteins meat has but beans has some and rice has the other

Ask the teacher they will you
