Vegetarianism and veganism are probably more popular now than they've ever been. However, if you're not ready to make the switch completely, then we don't blame you; meat is pretty delicious. But it's also usually more expensive than buying produce. So, if you're looking to save money, then you might want to consider having at least one vegetarian meal a week. You can increase the number of meals if you feel like you want to save more money.
The best thing is that there are now plenty of websites and videos devoted to strictly vegetarian recipes, meaning it's not going to be very hard to find your next favorite meal.
