I think the answer to what to avoid is pretty clear: anything that is not Ital.
I don't have any links to recipes, but you can search this site for threads discussing Ital foods. Ital food doesn't have to be complicated, just use natural and healthy ingredients.
First I would start with ceasing alcohol and salt completely, processed or bleached foods, anything with GMO ingredients, and all meat and egg and milk products. The cleansing can start once the body is not having to digest these toxins and the body sometimes becomes tired after the trapped toxins are coming out of the organs (flooding the bloodstream) and then making their final exit from the body. After the one month point this fatigue usually ends as long as the person is eating enough fats like avocado, olives, and nuts (which digest slowly, giving the body a slow-burn of constant energy).
Recipes are going to depend on what you can find. It is best to grow your own fruits and vegetables or to buy organic local ones when they are in season. Many health food stores will label their local produce so you can look out for that if you don't have farmers markets in your town.
I think there may be some controversy in the vegan world about eating grains and beans, especially with all of the raw food and gluten free food trends. But I still follow the traditional vegan rule about mixing grains and peas to get a full range of amino acids. Some awesome grains to try are quinoa, teff, black japanese rice (sometimes called japonica or forbidden rice), wild black rice, and kamut.
