While lizards mainly prey on insects and other small organisms rather than consuming vegetables themselves, they might occasionally take a nibble on certain types of fruits or leafy greens in your garden. Some vegetables that lizards may eat include tender crops like lettuce, spinach, and young shoots of plants like beans or peas. However, it's important to note that this type of feeding usually occurs if other preferred food sources are scarce. Furthermore, the impact is generally minimal since their consumption level tends to be low compared to the size of a garden and the abundance of vegetation available.
