If it's going to be hot tonight where you are, may I suggest cold sandwiches and salad? I'm thinking something like cream cheese with cucumbers and tomatoes. If you think salad is for rabbits, this broccoli salad is pretty filling and is a good one even for broccoli haters. I got this recipe from my mother-in-law after mowing through a bowl of it for lunch. It was the first time I can think of where I ate the whole salad before starting on my sandwich. It's that good.
4 cups broccoli
1 red onion (Next time I make this I'll use less than 1/2 of one)
1 cup sunflower seeds
1 cup raisins (golden or regular, but golden somehow make the salad)
1 cup mayo
2 T white vinegar
1/4 cup sugar
Chop broccoli, red onion and tomatoes. Mix with seeds and raisins. Stir mayo, vinegar and sugar and combine with veggies, raisins and seeds.
Another suggestion, double the recipe and keep it around all week since it's supposed to stay pretty hot around here. If you think you might take some of this for lunch, I strongly recommend using less red onion. Just trust me on that.
Note: In the spirit of full disclosure, technically this recipe calls for bacon, 6 crisp strips chopped and mixed in with the veggies.
