I've come up with a menu for that special date

Less than a week away is my son's girlfriend's graduation. We'll be hosting a dinner that evening for our family, my son's girlfriend and her parents, a total of 8 of us. I've decided on a menu. I took all of your comments and think I came up with something very doable for me.

It's high points:

• much of it can be done ahead (like the roll dough, the potato salad, chopping the rhubarb and vegetables)
• it uses some produce from our garden
• it also uses a cut of meat which I got a good deal on at Cash & Carry
• the menu is not too fussy
• it contains no dairy
• and it features some all-American foods, like pie and potato salad

Here it is:

Herb-crusted roast pork loin (Cash & Carry for $1.68/lb)

Potato salad (a very typical summer American food, and it's easy to make ahead)

Garden lettuce and spinach, garden strawberry, garden green onions, celery, toasted almond salad

Overnight dinner rolls

Casserole of summer vegetables (zucchini, peppers, tomatoes, onions, garlic -- these will have to come out of the grocery budget)

Watermelon pickles

Rhubarb and blackberry pie

I'll put out something snack-y, too, for before dinner.

I considered a barbecue, but our weather in the PNW can be so unpredictable in June. We're expecting more showers later this week, and that could bleed over into the weekend.

What do you all think? Any other suggestions or advice?
