Warning----these aren't the healthiest options, but they work for us with "vacation rules". (In other words, eating the junk we really would love to have all the time!)
I've learned over the years that Costco and grocery deli meals are my friends as well. It's a treat for me, and sometimes I end up ahead since I don't have to buy all the little "extras" that you normally have in a stocked pantry at home.
Breakfast- bacon, eggs, pancakes. We rotate these things and buy the just add water pancake mix. Sometimes we just buy muffins instead.
Lunch - Sandwiches, mac and cheese, heat and eat deli meals, chips/veggies and hummus, sloppy joes, quesadillas & chips and salsa
Supper - Usually we plan tacos, spaghetti, and ham and mac n cheese or potatoes, ham and cheese sliders, pineapple bbq grilled chicken and baked potatoes, jambalaya with smoked sausage, pizza....
One of my favorites is sausage tortellini Alfredo and it's really easy for timeshare stays because it only takes 4 ingredients and it heats up so well for lunch leftovers.
1 lb bulk sausage (we prefer a spicier blend)
1 package cheese tortellini
1-2 jars Alfredo sauce
1 bag of frozen peas
Brown sausage and boil tortellini while browning sausage. Place frozen peas in bottom of colander. Drain pasta over frozen peas. Add sauce, sausage, and return to heat until heated thoroughly.
