If you are making something that is fried, you should place the food on a paper towel before consuming so that it can soak all the excess oil.
Rather than frying, try baking. It is a great healthy alternative that gives you the desired crispy and crunchy end product.
Purchase non-stick cookware, as they require you to use less oil to cook. The material of such utensils prevents the food from sticking so you don't need to add excess oil for greasing the pan.
Instead of sauteing your vegetables in oil you can use water or vegetable broth to do so. This will further help you cut down oil usage
This is a great option for meat and tofu. Invest in a grill so that you can cook your meat and other vegetables without using oil and compromising on the taste as well.
