Way to go on your big healthy shop! Some veggies stay fresher longer than others...I have a trick with berries I wash and dip them in vinegar - keeps my strawberries good for a full week.
You should google some tips about that and easy stir fry recipes - super simple I think you will do great and are on a great start.
A lot of people would be jealous of your figure...you have great curves. =) Never forget that our metabolism slows down with age..I have to try waaay harder than I did when I was in high school and don't think I will ever get back to that weight now that I'm an adult. I think walking will tone you up in no time and you should try to add a tiny ab workout and just do it every morning before you shower. 1 week of exercise and healthy diet, you will see some abs showing!
Keep up the great work! Whenever I start to lose motivation I plan an event I want to look good for or think of my bikini LOL
