Summarize:

The best part about uromastyx lizards is that they eat foods that can be picked up from the grocery store. The bulk of your lizard’s diet (80%) will be made up of dark leafy greens. Some good choice include:  Bok choy. Chard. Beet greens. Spring mix. All greens should be rinsed and torn into pieces. In addition to greens, you can provide your lizard with a mix of veggies. This helps to make sure that they are getting a diverse selection of vitamins and nutrients. Use organic produce, whenever possible. Greens should be sprinkled with a powdered calcium supplement for lizards.  Some good choices include:  Pumpkin (chopped or grated). Yellow squash (grated). Zucchini (chopped or grated). Sweet potatoes (chopped or grated). Carrots (chopped or grated). Peas. Green beans (chopped). Veggies can be served raw (either chopped or grated), but should be washed. The vegetable species called "brassica oleracea" includes broccoli, brussels sprouts, cabbage, and cauliflower. Brassica oleracea vegetables should be avoided! This species of vegetable can cause digestive problems in lizards, as well as kidney and bladder stones.  Kale is also part of the brassica oleracea group, but kale can be served occasionally, in limited amounts. These vegetables won't be toxic to your lizard, but you should still avoid feeding them to it in large amounts. Uromastyx lizards are primarily herbivorous, and will get most of their nutrients from plants. Protein from insects will only make up a small portion of your lizard’s diet. You can provide insects (such as crickets) for an occasional treat 1-2 times per month.  Adult uromastyx lizard tend to really enjoy insects, but over-eating these can cause major digestive problems. Insects should be fed live. Avoid giving your lizard insects more than 1-2 times per month! Purchase a few crickets at a time and feed them to your lizard right away. This will help avoid over-feeding. Crickets and other insects can be purchased live from your local pet store. Calcium is important for lizards because it protects against metabolic bone disease. Look for a calcium powder designed specifically for reptiles and sprinkle it on vegetables before you feed them to your lizard. Uros are accustomed to an arid environment, and they don’t require a lot of water. If your lizard is consuming greens daily, the majority of their water intake will come from their food. To provide a bit of extra water, you should mist the inside of their cage 1-2 times per day. You can also provide a small dish of water, but it should be removed from the cage after one hour.
Provide leafy greens. Offer vegetables. Avoid broccoli and related vegetables. Provide insects as an occasional treat. Include a calcium powder in your lizard's diet. Provide a little bit of water.
