You can vary the amount of veggies below. I am only giving approximate numbers. Beets, parsnips, turnips or eggplant might also be good additions.

15 new potatoes – cut in half
10 tomatillos – paper removed and cut in half
2 zucchinis or other squash – sliced
2 sweet potatoes – peeled and cut into chunks
5 carrots – cut into chunks
Hot pepper – sliced. only some seeds included.
2 garlic cloves – minced
1 onion – coarsely cut
1/4 cup olive oil (or to taste)
fresh chives
fresh basil
pepper
small can of tomato paste (critical)

Mix everything together in roasting pan. Cook at 400 for about 1 hour 20 minutes. Check and mix veggies every 20 minutes or so. Great as a main course with salad and bread.
