Company Coming

My aunt and her friend are driving up to visit me on Saturday. I want to have a casual lunch ready and then something easy to prepare for dinner.

For lunch: pasta salad, sandwiches, hummus

I'm stuck for dinner. I don't have air conditioning, so I don't want to use the oven, or even the crock pot. I guess that means grilling, which intimidates me a little. I haven't used the new grill. It's a portable gas grill. Oh well, I'll be brave and try.

Possible dinner:
Romaine salad
Potatoes (I can peel these ahead of time and put on ice)
Flat iron steak (I already have this in the freezer.)
Frozen strawberry pie
