Try easy Mexican:
Toss a bunch of tortilla chips on a microwaveable plate. Sprinkle with shredded cheddar and mozzarella cheese (mehadrin makes a bag of the combo), open a can of any kind of beans and toss some on top.
Microwave for 1 minute.
You can add some mild salsa or diced avocado if you’re ambitious.
You can do grilled cheese or “pizza” grilled cheese in your toaster oven.
If you don’t like to cook you can keep sliced lox or store bought egg/tuna salad in the fridge with a bag of whole wheat bagels and make sandwiches, or ww bread and smoked turkey.
Buy yourself pre-cut peppers, baby carrots, grape tomatoes so you don’t have to think about dicing veggies. Eat with low fat dressing.
