I have salads most days- spinach, cucumber, tomatoes, carrots, pepper and some kind of protein usually eggs or beans, plus I try to keep a stash of fruit at work for snacks. I try to mix up my shopping with different veg each week so I'm not always eating the same thing and getting fed up. It works with sturdier veg too just roast up the night before you can use onions, peppers, courgette etc. Roasted celery is actually really tasty and so different to raw.

-I like to buy chicken cutlets, season with fresh basil, garlic, kosher salt and onion. Bake all, and freeze for the week. They can be used with salad, sandwiches ( I get a flatbread called Fold It and put either hummus or opadipity dip instead of mayo), quesadillas, tacos, or with a veggie and grain. Sweet potato is filling. I usually have a pre washed box of spring mix salad on hand and use it for the week. Can by used to make a salad or add to tacos and sandwiches.

-Tuna and egg salad with a fruit on side are filling
